10 Best American Dad! Characters Only In One Episode

Ah, Steve. When will you learn that hot girls don't hang out with nerds?

Easy to see why he'd be confused, though. He and his friends spend much of their winter break with a new Swedish exchange student named Sllort, who, despite being disproportionately attractive amongst Steve's crew, has fun sledging with them before they go back to school.

Their little monster friend, Billy, is quick to point out that Sllort, who speaks in poetic, riddle-like sentences, is going to ditch them the minute school starts and she realises there are better options. Steve tries to prevent this by framing her for some graffiti, but it backfires in the worst of ways. She's expelled, and when a dead body covered in strange runes is found with the paint cans, the police show up to arrest her.

Meanwhile, Billy investigates the runes and comes to the conclusion that Sllort is really a troll, exclaiming, "Her name is even 'troll' backwards! Well, 'trolls'." She committed the murder, and when the police's prime suspect is also found dead, Sllort is released - just as Steve thinks to confess about framing her.

Revealing her true form, she chases the gang into her 'murder cave', only for the ceiling to give way and knock her unconscious. Because they save her, Sllort decides not to kill them, but still won't rejoin their group, her reasoning being, "Yeah, about that. I'm...hot."

Probably should just quit while you're ahead, Stevie boy.
