Apparently, he does
I hope he could appear at least on his Birthday doing...something
Maybe they are doing those reshoots....I would love at least some new scenes from Loki, but I am afraid it may be a while since we do not have the release date for the show yet.
There are new rumours he may be in post-credit scene in Ant-Man but we heard those before for some others. I am a bit more hopeful here because those were filmed together with Loki S1 (isn´t it funny how S1 was in 2021 but Ant-Man is not out yet?). But I am not holding my breath
The Ant-Man and the Wasp: Quantumania ending and credits scenes might have leaked, teasing massive multiverse developments.
