So, just when we thought that would be it for the water balloon gags, a new twist arises. It was one of those random unlasting moments where you just suddenly have superhuman reflexes for a moment. This time Wally didn’t even worry about it, but he did call out “frozen” water balloon. Maybe that validated it, as long as you call it. Like perhaps “hey, I’m throwing the equivalent of a heavy rock right at you” gives total fair warning.
