Gideon left without much of an explanation (mainly because Mandy Patinkin wanted out very suddenly). Rossi (the new guy) will take some time adjusting to. Mind, he's no Gideon, but eventually he'll bring his own contribution to the team.

I read Reid/Morgan in a very sibling way. Morgan loves Garcia. Can't go there all the way, but she's the closest to a lover he'll ever get, I think.
