(Doubtful I know)

Yeah, slightly random I know, but I've been using the MCU digital app lately so checking up on things I've never bought.

I've just started reading Secret Warriors and in the back of #1 it has a bunch of infographics, one of which includes:

4627

So it looks like Hickman had them planned from the start!

Jenny Munroe
Malcolm Munroe

I haven't read the issue in question, so could there be the chance for more pre-death flashbacks of them in the rest of the arc?

Yeah, comicvine seems to support your logic, so I guess it's pretty much official :D

Nice spotting!

Was there an image of Flashback at all, or just mention of him?
