He just assumed Rick was dead because the heart monitor went off when the power shut down. He tried to get him out of there initially. He panicked and left Rick in the room after making sure the Walkers couldn't get him. He definitely didn't 100% think he was dead.
I'm not blaming him for leaving Rick there, if he'd tried to get him out, it would have slowed him down and they both would have probably died. But the point I'm making is he lies. A lot. If you like guys that lie and rape that's totally fine with me, help yourself. Just stating opinion rofl.
The longer he is alive, the more I detest him.
I really really liked him in the beginning, too...
This is Shanes last season, they accidentally released some promo material for the blu ray disc and John Berenthal is cast for a different show now
Tv Shane did live a hell of a lot longer than Comic Shane though
I didn't want to read the comic until someone told me Shane dies in it. Now I'm trying to scrape together money for it! hahaha.
