I think the only sucky thing about this episode is at the end where he vanquishes barbas because he KNOWS the sisters can't and they look at him like he's some evil creature who should eff off.
I'm sorry but I completely blame the sisters for his inevitable trip to evildome again. Well maybe 90% their fault, obviously he made his own choices but he doesn't belong in the world and the only people who he can talk to about his feelings shut him down and TELL him he's evil no matter what he does. God Cole could probably save a bus full of kids, donate all his money to charity and solve world hunger and still be told he's evil instead of thanked.
I'm not a big Cole supporter during season 5, while I like him, I feel the drama they try and create and making Phoebe look like a cow is annoying, which makes me not like her which makes me angry at the show I guess because she's actually a good character.
And Paige did nothing wrong here. She stripped his powers not like she was told "btw they'll go to Barbas" and she was all "meh who cares". And the other two only made their decisions because of Barbas anyway.
But I love this episode, Barbas is an awesome bad guy, I especially love him when he's the demon of Hope
