Damon and Tessa in “Unfinished Business”

Damon

So here's my pitch. In order to keep the other side in place, you need something to anchor the spell, right, something powerful, like an immortal being powerful. Now Amara was obviously a great choice until she downed the cure, so would you consider someone who's dead but stuck on the other side a viable candidate?

Tessa

An anchor swap?

Damon

Because I've got a volunteer.

Tessa

I'd be making a ghost a human toll booth between our side and the other side, giving her the power to interact with our physical world and the supernatural purgatory.

Damon

So what's the problem?

Tessa

I need a massive amount of power to do a transfer spell like that.

Damon

Fine. Name your poison.

Tessa

I need something to draw on. The moon's not full, I don't think there's a worthy comet for another couple billion years.

Damon

think hard. I have a girlfriend at home who misses her best friend and a wacky stowaway on suicide watch. It's ridiculous.

Tessa

Doppelgängers. They're powerful, mystically, naturally recurring.

Damon

You want Doppelgänger blood? I got Doppelgängers coming out of my ears. How many do you want?
