As I said in my previous post, [spoiler] Amanda will be back, unfortunately. [/spoiler]
I honestly wished that Quentin had allowed Angelique to carry out her threat against Amanda. Not only would we be rid of Amanda forever, Angelique really wouldn't have anything left to threaten Quentin with. Then again, there IS Beth, but does Quentin even think of her anymore? He might not even care about her anymore, seeing as she tried to kill him.
So now Petofi has taken away Tate's ability to paint great. To Tate, losing this ability may be the end of the world to him, but he's gotten off with a slap on the wrist in contrast to Petofi's other victims: Petofi's possession of Jamison then possessing him with the spirit of David, kidnapping Julia, then tried to have her killed twice, possessed Charity with Pansy, caused Edward to believe he was a servant, ordered Barnabas' death, set Magda up to be killed by King Johnny and so on and on.
Some may feel sorry for Tate, but I can't say I do. He knew that Petofi must have wanted him to paint Quentin for a reason, so it should have occured to him he'd be pissing of Petofi as well as Quentin by taking the portrait.
