my head hurts!

It's pretty easy to understand as for who Zoom possibly really is

^please enlighten us.

The first part can't spoil it, as for Zoom all I can say is it's not any of main actors playing Zoom when you see him it's a stunt man in the suit and parts of the suit are CGI that's as much as I can about it lol.

^^voiced by the great tony todd.

it is shame that we don't get to see much of zoom.

That's because it's being saved for latter Ep's of season 2 starting from Ep 15 and it's been posted that it's Tony Todd several months ago.
