The "Other" Castle Couples

Yes, we're as madly in love with Caskett as you are. But this Valentine's Day, we're thinking about all the other couples who've made Castle sizzle over the years. Who's your favorite?

LANIE AND JAVIER

The precinct's on-again, off-again couple seemed to be back on this Valentine's Day, but with these two, you never know what the future holds. Either way, we're sure it will be a fun, sexy ride.
