I wouldn't call it a cliffhanger.
it's just a first 12 seconds of next month.
Aarons plan seems to be to never show the story form Banners perspective.
Hulk tries to stay angry for as long as he can until...
Weeks months possibly rush past.
Angry again, look left, look right... Banner is suuuuuuuuuuuuuch a cock.
It's how they did Batman under Adam West and how they did Alias with Garner.
Preview not cliffhanger.
A cliffhanger is, in my opinion, is a break half way through the story, not 1/2 a second after the bugger starts.
