hmmmm yeah i never thought of that before i really think she wouldn't come because she knows that she is not strong and infront of the Konoha 5 she can't do anything except that stupid "Cancel" Genjutsu. and plus Lee wouldn't let her go. and Plus Lee is gonna go through that treatment....and Tsunade said it will take long time. So i don't think he'll be able to fight right after the treatment.
