'Steve mets the justice league, is perplexed' is such a delightful idea and so true, because he'd just be standing there going "... what ... why ... i was on an island of amazons can i just go back to that". I also really like the idea of Steve being on Themyscira for awhile. That would be HILARIOUS.
Right?? Also I’d watch an entire movie of Steve washing up on the shores of Themyscira and the Amazons being like “crap we have this man now what do we do with him” and Diana is all “I’ll show him around!” and we get a lot of Steve’s “THIS IS INSANE” while they go to banquets and jump off cliffs and what not.
