I believe Feige isn't going to clutter up Homecoming with other young superheroes. Last thing I want to see is young Nova and this White Tiger miss as I couldn't stand USM after a couple episodes. To this day it baffles me why they canned TSSM for that load of rubbish but that's another story.
The reports say as everybody else read that Revolori is playing Manuel, not Samuel and the only Manuel I've seen is that of Hobie Brown aka Prowler's younger brother. Why can it not be him or else if Hobie is not going to be a part of the series, maybe Manuel could become Prowler himself?!
I don't want the classic supporting cast including Flash, Liz, Kenny, Sally, Randy etc being pushed to the back in favour of these later additions, but I don't mind this Zandaya chick playing Michelle being Parker's flatmate and maybe Laura Harrier as Liz too. I'm pretty excited for this Breakfast Club like movie version of Spidey which is such a great idea.
