Under the Dome: Watch Season 2 Episode 3 Online

at . Comments

It's raining red acid on Under the Dome Season 2 Episode 3. The townspeople initially believe it's raining blood, but Rebecca quickly determines it's acid instead. It burns the skin something terrible.

A conflict between religion and science is raised over the red rain. Is it a sign of the coming rapture? Or is it from a build up of algae in the lake? Given the different thoughts, it could actually be a sign of both. Weird, right?

Several outstanding questions are answered at least in part over the hour, but they raise even more questions for the residents of Chester's Mill.

Watch Under the Dome now.
