User blog comment:ImperiexSeed/Castiel's shifting of Sam's mental problems made no sense!/@comment-2020973-20120402231131

I think Cass just absorbed all the tramatic memories Sam had. If Sam still had the memories of hell and Lucifer then he would still be going into meltdown mode because the memories would be damaging him. Angels have shown to be capable of manipulating memories before so why can't they absorb them as well?
