For the ones who have read ''X-Men Origins'', I have many questions about Gambit's story.

1- What are the names of all the people that Gambit gathers for Sinister?

2-In the sewers, is Gambit saving from the dead the young Marrow or is it somebody else?

3- I don't understand the totality of the chapter 4.
->Is it Storm that is falling from the building?
->Who are the three characters that have come after her falling? What do they want to the woman?
->And why does Gambit absolutly want to remember what happened?

Thanks in advance to the one who'll have the patience to answer! :)
