(bad English and long text)
I understand that I'm probably far from the first person to say this, but one of the few things that genuinely touched me in MP100 was the moment in the "Claw" organization at the end of season 1, where Reigen told Mob to run away. I understand that he was most likely just broadcasting his self-preservation style – "flight" – but personally, I saw something different in it and my heart still aches with joy here. Reigen told him "you don’t need to take this all on yourself, let the adults handle everything."
As the oldest sister myself, I understand what it’s like when parents leave their other children to you, giving birth to them with the default thought that you have already grown up as a helper, while you, for example, are 11 years old. Mob's situation is different – there is only a year difference between him and Ritsu, but judging by the way Ritsu reaches out to him, takes his example not only as an esper, constantly emphasizes that Shigeo is his older brother (I can't speak for everyone, but I still don’t really perceive my older cousins, who are ~4 years older than me, as an elders, but as peers), and also from the apparent complete absence of parents in the boys' lives, I can assume that all his life Shigeo has been left to his own devices at best, and with Ritsu in his care at worst.
I don’t think that their parents are completely indifferent to them – they attended their school race after all – and I haven't read the manga, so I can't judge with certainty, however they have catastrophically few appearances in the anime, besides the standard dinner scenes together (my friends even joked while watching that "these NPCs at the table have one script about spoons"💀 lol).
Mob's whole story is about how he gradually develops his personality, learning to express emotions. But I don't believe he suppressed them solely out of fear of harming someone with his magical outbursts.
I know how children mature beyond their years behave, because I was one. Mob always acted like he was too burdened for his age, having restraint uncommon for kids. He himself disliked this fact, and it was a hard-fought battle to loosen the internal grip. All because this is the consequence of too much of a burden that good-natured but absent parents could've placed on him (I mean, come on, your child – the most powerful esper in the universe – disappears for days and sometimes nights, occasionally even with his brother, and not only do you not know this, but you also keep repeating your spoon script?).
This is where Reigen comes in. Little Mob needed guidance, advice from at least someone who could understand what to do with his gift and his life – and Reigen, not yet knowing about his abilities, gave him this advice, which he listened to with his mouth open. It was clear from that scene how much Shigeo needed support and guidance, and frankly, a parental figure. Real parents, as I wrote above, don't seem to care at all that their son easily comes home late at night or even in the morning, nor did they show any interest in his studies or hobbies. Maybe I'm wrong, please correct me on that, but it's really so little of them in the series.
Reigen, be he thrice a manipulator and swindle, saw a child with a truly divine gift, and his first instinct was "I can make something out of this." Mostly money. But as it turned out later – a good person too.
And Reigen's parenting abilities can be judged by the fact that Mob not only turned out to be a good person himself but also was able to guide others by his example – for instance, Teruki.
Even if we take into account the fact that Reigen never failed to use Mob’s abilities, relying too much on him, he still took care of him: he always treated him to food, never smoked around him, came to pick him when he had problems, stood up for him (in the episode where Mob was almost scammed in the vase incident by con artists, who did he call first? Not his parents, no. Reigen).
And finally that scene in the "Claw". Reigen told Mob to run away because the problem he was getting himself into was an adult problem, as he himself said. He literally said that Mob shouldn't act against his own morals, because he is still a child, he hasn't grown up to make such decisions (and it was clear how difficult it was for Mob to decide to harm someone from those espers, because it went against everything, what Reigen taught him). That's why he freed Shigeo from this responsibility: run away, leave it to me, kid, I'm an adult and you shouldn't risk anything and challenge anything in your heart.
Reigen may be a scammer, but he could put a lot of parents to shame. Including mine (in our translation he even literally said in that episode that he is Mob's "acting guardian", my gooood 😭😭😭). I wish having someone like him growing up, someone who can willingly take responsibility when it's necessary.
Thanks for coming to my Ted Talk.
I'm a little late with this
TW: Reigen mentions his PP, talks of anxiety
bf!Reigen x gf!reader where reader is feeling anxious and Reigen comforts her
You were curled up in bed, doomscrolling, practically pouting, mute, and ignoring your annoyingly unserious boyfriend. He hadn't done anything wrong, you were just stressing about work, already dreading the day that had yet to happen. You knew you'd be alright, you were always alright, and you also knew that you should talk about it instead of silently brooding, but old, bad habits died hard, and no amount of reasoning or rational could pull you out of your glum mood.
"Hellooo," Reigen called out tauntingly. "Anybody home?" He laughed, collapsing over your lap and crushing you with his weight.
You glared down at him momentarily before resuming your doomscrolling, though you were hardly paying any mind to what was on the screen now that he was demanding your attention.
"Yikes." He raised his eyebrows. You made a sound of protest when he snatched your phone out of your hand, locking it before tossing it aside on the bed. "You want to talk to me about something?" Reigen kept his cool and cocky facade, but you didn't miss the way his brows furrowed slightly.
"Sorry," you mumbled. "I just don't feel good right now." You avoided his prodding gaze.
He rolled off of your lap and shuffled to your side. "You need me to get you something? Water? Food? Motrin?" He studied you innocently.
"No, not like that." You smiled a little. For as goofy as he was, he could be so caring and gentle when the situation called for it. "I just feel so anxious right now," you sighed. "That's why I'm acting so bitchy." You cracked a sheepish grin. "Sorry."
Reigen laid on his side, propping his head up on his hand to look up at you. "That's okay. It's cute when you act all bratty." He grinned too, making you roll your eyes. "Talk to me though. What's bothering you?"
"Just work." You shrugged. "I don't want to have to deal with that project I was telling you about." You frowned.
"You can always come work for me." He wiggled his eyebrows. "I could use a sexy receptionist."
"Be serious," you groaned dramatically, suppressing a giggle.
Reigen smiled, snaking a hand under the blanket to caress your thigh. "It won't be as bad as your brain is telling you it is," he explained matter-of-factly, softly massaging your skin. "It will come and go, the same way it always does, and if you have a stressful day, you know I'll make it better tomorrow. For now, you're here, and you look super sleepy and pouty and adorable, it's making my junior throb..." He squeezed your thigh for extra measure.
"I hate when you call it that!" You giggled loudly. "You pervert!"
"Yeah, I just wanted to hear you laugh." Reigen grinned stupidly. He sat up, grabbing your face, squishing your cheeks, and making a show out of kissing your cheek, nose, and forehead. "You feel better yet, or do I have to kiss you somewhere else...?"
You playfully shoved at his chest. "You're so slutty."
"I was talking about your lips, the ones on your face!" He laughed. "I think you're the perverted one here."
"I learn from the best," you giggled. "Thanks for cheering me up." Your problems slowly fell to the back of your mind. Your anxiety would never vanish entirely, but it was nice that you had these moments and this man when it seemed all was lost. It never really was.
He kissed your cheek again. "No thanks needed. You're my girl. Happy wife, happy life, right?"
"I'm not your wife." You narrowed your eyes at him, but the smile that plastered your lips betrayed you.
"Not yet you aren't, crybaby."
