Just because you don't understand it? An "I don't know' or "I can't really comment on that" would be a more honest answer. Who is really even any 'expert' on how the mind works?
If Blain is being brought through a process of healing, is it not a legitimate avenue if it isn't through ordinarily prescribe avenues or instantaneous? If you think it is obvious that his mind is 'messed up' how would you recommend 'untangling' all the knots that prevent a clearer thinking? or is it simply just impossible?
I've often joked, 'take your meds,' but the humor in that is established in the tragedy of the thinking that the mind can be cured with a pill. The pill is the proverbial message saying, "I don't know what to do for you, and can't deal with you, really, so here's something to knock you out."
