Something I made for last Halloween!
"Fears, tell me fears, don't get me started
I get a little grey hair for every scare you share"
More of a hope then theory
But what if Marcy's body is just possessed by the Night and like her soul is free. Then Maddie can just summon her and we just have ghost Marcy. Or she finds a temporary vessel for herself. We can get some Sasha and Marcy bonding and an epic battle of Marcy fighting her own body.
When Alfred does his desire to ensure those under his care are well? That desire, that need? Is more than enough, that plus the ectoplasm in Gotham. He forms into a ghost in the Infinite Realms. This happens a few years before Danny opens a portal. More than long enough for Alfred to have grown into his strange new existence.
So when he heard of a stable portal to the living realm? Well he was curious. Did it lead to his dimension? And then well, he went to have a look. And found a young teen. Who looked so like Bruce. Who felt such a need to look after that which was his. And he couldn't help but need to look after the boy. In only a few short weeks the boy was already so tired.
This just would not stand! Absolutely not! so he left the portal and checked on his new charges house. And it was barely fit for anyone! So, he did what he always had. He took charge of ensuring the place was clean and orderly. Ensured their was good, safe food available. And ensured his new charges would be as well as they could. And if that included beating the idea that ghosts were sentient into Master Danny's idiot parents head? Well. That would only help him tell them sooner!
Young Master Danny was a stubborn young man. But that was hardly a surprise! He gave in, in the end. Alfred's cookies always won in the end. The prospect of safe food and a safe house? Worked wonders. Now, if Alfred could just figure out if this was his home dimension or not... Alfred could only give so much support after all. Only give so much advice. An experienced hero would be a better mentor. At least Master Danny was allowing him to help tend his wounds now.
