ok so ya Hyde is still scared of his situation and he is unsure of our gang due to… well you know, even though they were nice Hyde sees that they could be only nice to Jekyll and not to him, the flashback shows what Hyde wants first (the other side to how he lived in the streets will show later) Hyde (as well as Jekyll) learned that the life they had before was not as fun or worth it as they thought and caused them to be in this situation, they can still live like this BUT not as often and would rather live a life shown here. yet of coarse if Hyde wants to settle down he has to go to places to meet others but that is another story for another time.
yes it seems weird but this is to show that Hyde can be more then what he suppose to represent for Jekyll beck then but I won't say too much, for now, I rather show it someday.
and yes Hyde and Jekyll call each other by their first names and speak to each other in mind
