OK, so I've seen many blog posts mentioning Noah, Karen's son. But is he really Karen's son? I I re-watched "I ain't a Judas" and Karen actually doesn't say even once that Noah is her son, nor Noah is saying Karen is his mother. I think he isn't her son, only young boy whose parents maybe died earlier and Karen just tried to keep him away from fighting.as he had an asthma. This would explain why she wasn't depressed in finale, probably because it wasn't her own son.
