Oh, how we love to hate Michael Ausiello. Today, TV Line's spoiler guru tweeted a mysterious blind item from a couple months ago about an on-screen non-couple who will finally seal the deal — read: have sex — in an episode airing during May sweeps.

Naturally, the Castle fandom was on high alert, following Ausiello's every move as he engaged followers in an impromptu game of Clue.

Here are some of the juicy tidbits he delivered:

The couple is human
They will engage in foreplay before "hooking up"
It does not happen in a dream sequence
It will take place in a house, apartment, or loft
It will happen during the season finale
The show is neither in its first season, nor in its tenth
Some fans will be pleased, while some fans will say it happened too early
The show is not on CBS
The show is a drama

Taking into consideration Stana Katic's promise that Castle fans will be "really happy" by the end of the season, we're inclined to believe the blind item is about our beloved Rick Castle and Kate Beckett. But at the same time, we don't want to get our hopes up.

What do you think? Will Caskett seal the deal in the Season 4 finale?
