After Abomination was beaten by Hulk in The Incredible Hulk, we never heard about him. So, it's safe to assume that S.H.I.E.L.D. took him in custody somewhere classified.
S.H.I.E.L.D. is out of commission. Also, in Marvel's Agents of S.H.I.E.L.D., it is shown that the Fridge had fallen, freeing all supernaturals locked in there.
Can we assume that Abomination is also free now? Or is there any glitch with this assumption?
