One of the unfortunate side effects of being a human is getting sick, as newly human Katherine is about to find out on The Vampire Diaries.

In an all-new sneak peek of Season 5, Episode 2 (“True Lies”), via TVLine, Matt and Jeremy get stuck babysitting Katherine, but this doppelganger isn’t going to make things easy for them. After all, she may be human, but Katherine hasn’t lost her sly ways — despite suffering from a headache, scratchy throat, and green tongue. As she slips into the bathroom, we have to wonder if there is a conveniently placed window for her to slip out of because Katherine isn’t one to take orders.

However, we’re more interested in Matt. At the end of last week, we were unsure what Nadia and her accomplice had done to him. Had they stripped him of his humanity? In the clip, Matt appears to be agitated. Of course, he did get stuck taking care of Katherine, so we’d understand if he were upset. Not to mention if Matt did have something supernatural happen to his brain, wouldn’t Jeremy be able to sense it?

Meanwhile, back in Mystic Falls, the hunt to find Stefan is on — and both Damon and Elena are suffering from hook-up guilt. Damon asks Jeremy and Matt to keep Katherine out of sight, while he tries to locate Stefan. It seems that Damon had a change of heart about turning over Katherine. Does he know what Silas wants from her?

Watch the full sneak peek below, and tell us what you think. Is Katherine about to run away from Jeremy and Matt? And what do you think Silas wants with Katherine? Sound off in the comments!
