*Spoilers*

At the start of Episode 2 we learn that the outbreak could have started at the flour mill in Jakarta.

In Episode 1 Joel's daughter didn't make him pancakes for his birthday. Joel and Sarah both refuse to eat the biscuits their neighbors made (the grandmother later turns). Sarah doesn't eat the cookies the neighbors make, and Joel forgets to buy himself a birthday cake before he comes home.

Thought that was a pretty nice touch.
