Will Beckett Admit She Heard Castle's "I Love You" Tonight in Season 4, Episode 16: "Linchpin"?

There’s been a ton of speculation about tonight’s Castle episode, Season 4, Episode 16, “Linchpin.”

During the end of the epic two-parter, Castle, Beckett, and their third wheel CIA partner Sophia Turner (Jennifer Beals) will collectively solve the mystery of a deadly international conspiracy. But from the sounds of it, many fans think there’s another big reveal coming at the end of tonight’s ep: Beckett admitting she heard Castle’s “I Love You.”

The smart people over at TVLine think the Beckster might say something like, “So tell me, Rick, did you love her, too?” in reference to sexy Sophia, who we found out last week shares a steamy past with Mr. Rick Castle. Other fans on Twitter think Beckett will spill her guts to Medical Examiner BFF Lanie (they did chat off-screen last ep about Castle and Beckett’s momentary tiff), or someone else dear to her heart (that’s not her therapist).

What do you think, Castle fans? Will Beckett admit she heard Castle drop the L-Bomb on tonight’s ep?
