While we're pretty sure Aria has just contracted a nasty bug, we're kind of intrigued by the prospect of one of the Liars finding themselves in this situation. While teen pregnancy can easily slide into embarrassing melodrama, Pretty Little Liars actually has a good track record of dealing with more serious, realistics subjects, despite its more fantastical elements (Emily's [Shay Mitchell] coming out arc being the most obvious example).
On the other hand, there's already plenty of craziness going on in the PLL world. Aria, especially, has her plate full dealing with "A", her possibly evil dad, and the kid Ezra (Ian Harding) already has.
What do you think: Would you like it if Aria were pregnant, or are you glad this plotline is almost certainly a no-go?
