Alfie probably thinks it might give you more of an advantage in a fight if you know the types of things Stein does. He knocked me out and drugged me after calling me to somewhere private. When he lobotomized Rhys, he got him alone. You want to make sure you have someone with you if you're dealing with him and never let him get you alone. He tends to isolate people and then conduct surgeries on them.

[John hears that sniffle.]

And just... like I said, please don't take it personally if he's a git again. There's something else that's probably playing into all this. Happened just before you arrived around the same time. Fiona was someone he cared about a lot. The Joker murdered her when she was alone. No one wants a repeat of that.
