She flips a coin to determine whether to kill Tyler or Matt, but Tyler angrily stops her. Caroline continues to pick a fight with Tyler until he grabs a stake and tries to stake her. This plan fails, however, as Caroline grabs Matt and uses him as a shield in which Tyler actually stakes Matt instead.In I'll Wed You in the Golden Summertime, Caroline apologizes to Tyler about everything that happened while her humanity was off. Tyler forgives her, and jokingly tells her that getting tortured by his ex and her new boyfriend is never good for the ego, as she quickly responds that Stefan is not her boyfriend. He tells her that he can't keep up with her and Stefan, and she apologizes again. He tells her that she's good. Liv interrupts them and Caroline leaves to make drinks. When she comes back, Liv is gone, and asks Tyler what he did. He tells her that he didn't do anything, but Caroline doesn't believe him.
