This was originally meant to be a 100% goofy funny comic, but somehow it turned into angst halfway through. I still think it's funny that Minimus canonically learns the truth before Amber and James though.
(And thanks to @ograndebatata for helping me rewrite the script to be more fitting).
Comic Script: Roland: … So, now you know the truth about my first wish on the well. I'm sorry I didn't tell you before. If any of you has anything to say, please do. Roland: Okay… one at a time please. James: Does this mean I'm half-wishing well? If someone put a coin in my mouth could I grant their wishes? Roland: WHAT?! NO! Absolutely not! Sofia: I'm sorry dad. Minimus and I already knew, and I think he has told every horse in the kingdom by now. Roland: That's not… how did you…? Amber: Daddy… does that mean I could have killed Sofia when I turned her into a cat? Would she be dead because of me? Roland: No Amber. That wouldn't have happened. Don't worry, no one got hurt. Amber: But Sofia almost was! Roland: But she wasn't. She's alright. All of you are. I'm sorry I only told you now. but please remember we both love you all very much. And we'll all get through this together.
