The Flash: Easter Eggs and Other Things You Might Have Missed In "Killer Frost"

Tonight on The Flash, Kevin Smith brought his signature touch back to The CW and, among other things, revealed the answer to one of the big mysteries that has driven the first half of the season.

And as always, we did our best to keep track of them.

So...what did we see? What did we miss?

Read on, and comment below.
