The right thing. Lexi wasn't entirely sure what the right thing was in this situation but whatever had happened with him and Elena had left repercussions that haunted her friend even here.

Even if this one hadn't actually done this.
"I know you loved her, a real love, more than you've loved anyone in a long time, but babe, you're gonna get through this. I promise you that, okay?"
