I'd have to say boo. The only great parts are Joshua saying, "tricks and treats", saying 'whoo hoo' at reading the book and him screaming at the little girl.
The whole episode, in reality, didn't happen and only faces what we already knew, it sucks to be a tran. Also the X-Series have it easier than the trashumans; they told us that when they very first introduced Joshua.
I don't even like to rewatch it.
