I think everyone has a very good idea what he wants to do by now, he's had months to sign a contract and hasn't yet and has told no one of his intentions. Didn't Sam say he was going to talk to Ross when He was first made manager, yet now Sam is saying he still doesn't know what Barkley is doing, that's stretching it a bit ! Finch Farm must be an awfully big place.
I imagine Sam and Ross talking and Ross being like a spoilt 13 year old teenage boy. Sam asks what's going on, you staying or going, and Ross with his head down mumbling, I dunno. Sam asks again, Ross runs away crying complaining that everyone's on his back and it's not fair.
So Sam still has no idea what the kid's thinking.
