The Vampire Diaries' Joseph Morgan on the Fallout of Forcing Tyler Out and Katherine's Return

Is all hope for a Klaus-and-Caroline friendship officially gone?
In one of the most heartbreaking Vampire Diaries scenes, Caroline (Candice Accola) and Tyler (Michael Trevino) were forced to say goodbye — yet again — so that Tyler could leave town before Klaus (Joseph Morgan) could kill him. While it seems this act would be one of many final straws, Morgan says the dynamic between the two is much more complicated than that.

"There's always got to be a hint of hope [for them], hasn't there?" Morgan tells TVGuide.com in the video below. "I would like to think that she is understanding enough [because] this is the thing: No one is truly good or evil. There's always some redeeming quality somewhere, maybe buried very, very deep within someone. I was filming a scene with her the other day, so the characters are still interacting. Their relationship, and I'll use that term loosely, becomes much more complex the more we go on, which is so interesting to play."

While the trio's drama was playing out in Mystic Falls, a very big enemy of Klaus' was returning out on the island. Just as Jeremy (Steven R. McQueen) was trying to get the cure free from Silas' fossilized hands, Katherine swooped in, grabbed the cure, and was gone before Jeremy could breathe his final breath. What does this all mean for the hybrid who despises the doppelganger? "Well, there are going to be interesting developments with that," Morgan says. "We've got to bear in mind this is someone who Klaus hunted down for 500 years. So she's going to want to do everything she can to avoid him, whether that's trying to kill him or make peace with him or trying to broker a deal with him, that remains to be seen, but absolutely not something that's brushed over."Watch this week's Vampire Diaries Bite: Can you forgive Klaus for his actions toward Caroline and are you excited that Katherine came back?
