I think they should cause they are just perfect together, deep down they both know they still 爱情 each other:) Tara and Ben just dont work he is sweet but just not like tara they wont last!
Christian - “He wants everything, I mean he wants Tink because she is awesome, she’s always there for him when he needs it. But I think deep down Peter loves Wendy,” Zach - “Why’s that?” Christian - “Because she challenges him to be better than he is. 你 know? He is scared of that so he gives her up, kind of makes him a sell-out”.
Actually if 你 check Their characters Wikipedia it says that Christian is Tara's boyfriend. So even though it doesn't 显示 that they are together in the last episode they actually are.
