Why the hell are you making a conscious decision to "play devils advocate" over such a sensitive subject if you get this pissy about disagreement?

As I said Ryan's behaviour directly contributed to Evan becoming sick, he wasn't just an innocent bystander who missed some signs. Even if the decision to dump extra work on Evan hadn't lead to him becoming so sick it still would have been irresponsible behaviour from Ryan.

Also no Evan wasn't good at hiding it, have you seen the interview he did with Conan around this time? The lad was visably exhausted. Ryan has literally talked about both him and Sarah being worried about the state Evan was in when they spent Thanksgiving together that year.
