I have never seen this envy streak in Banner before. It's troubling and obviously psychotic in it's own right... But what exactly is Banner going to do when he finds out that Maria and Stark have knocked boots? This new competitive streak is going to kick into overdrive towards her pants.
(Waid doesn't know, does he?)
Shield R&D is going to be creaming itself making specialised weapons for the Indestructible Hulk.
