ABC's Castle returns to our small screens in just a few short days, starting with "Significant Others" on January 7. And if that's not enough to cure your holiday blues, we've also learned that Molly Quinn, who plays brainy college co-ed Alexis Castle, will be live-tweeting throughout the episode!
 
"Yes, ABC has asked me to live tweet during 1/7 airing of Significant Others," Molly told a fan on Twitter.

We haven't seen much of Alexis lately — which may have something to do with her possible new love interest — but the Columbia University freshman will have plenty of face time in the upcoming episode. When a bad case of mono brings her back to Rick's loft (who have you been kissing, young lady?!), she finds herself in a packed house. Not only is Kate crashing at her beau's place while her apartment is fumigated, but Richard's ex-wife Meredith also shows up — unannounced, no less — and proceeds to make herself at home.

You know what they say — two's company, but three's a crowd! How will Rick handle two feisty redheads and a hot woman in uniform? Tune in on January 7, 2013 at 10 p.m. ET on ABC to find out. And don't forget to follow Molly on Twitter @MollyQuinn93 for all the behind-the-scenes dish!
