First, I nearly spit water all over my keyboard when I came across this picture from the official site. Pandering to the slashy fangirls much?
Second, what the heck does this line from the official recap refer to?

(Bad comma-abusing media type! No biscuit!)
My other thoughts on the episode are basically summed up in comments to this post of jonquil's.
