I agree. Really, if they pull it off, they've done it pretty well the way they've made Tim both right and clearly acting off emotions and denial. He says to Conner here that he's not going to "give up on" Bruce like he did on Conner but...that's just seriously screwed up. You don't give up on someone by grieving them when they've been shot by a gun that left behind a burnt-out corpse.
I would guess that when it comes to bringing Bruce back the family will come back together to get him. But I still wonder how they'll deal with Tim's plan that Bruce comes back and then things go back to the way they were when Tim was a couple years younger.
