Where did you hear that?
Where have you heard all this?
I know it for a fact.
Sterns is going to be a background character in this film or how LL likes to put it "the Wizard of Oz in our story". It is towards the end where we see him properly otherwise it is just emails (Mr Blue & Mr Green) and conversations where we come accross the name of Sterns.
Sterns plays about with Banner's gamma DNA making these gamma creatures and Banner is furious about it. He wants the Hulk dead not to have more gamma creatures (these could play a part in a sequel; Leader's mutant gamma army?). When Blonsky confronts Sterns for Banner's gamma blood, Blonsky attacks Sterns which makes us think he is dead but then as the Abomination, Sterns' lab is destroyed causing a big explosion and we see a shot of Sterns with his eyes wide open with a kinda of a smile I think with Banner's gamma blood (which I think has been altered with Sterns' experiments) dripping on his face. It is just a sign showing you that Sterns isn't dead and for the fans they know the Leader is coming.
Fascinating, Blonsky could turn out to be a greater character than I thought. He actually appears to be a dynamic character. I just hope he still looks like Blonsky before he turns into the Abomination.
