INDESTRUCTIBLE – Silas (Paul Wesley) happily announces his new goal to Damon (Ian Somerhalder) and Elena (Nina Dobrev), but they are skeptical when he promises to accomplish one important task in return for their help. Tessa (guest star Janina Gavankar) confidently tells Stefan (Paul Wesley) about her next move, then realizes that Silas has managed to outsmart her. A desperate Katherine (Nina Dobrev) discovers a new and unexpected consequence of becoming human again, and realizes she needs a new place to stay. In exchange for a spot in the dorm room, she offers to show Caroline (Candice Accola) how to get answers from Dr. Maxfield (guest star Rick Cosnett). Bonnie (Kat Graham) is touched by Jeremy’s (Steven R. McQueen) strength and determination to stand by her. Finally, Damon is stunned when he figures out the secret to Tessa’s plan. Jeffrey Hunt directed the episode written by Caroline Dries & Holly Brix (#506).
