Absence makes the heart grow fonder.
Sometimes you need to let someone go and see what else is out there before realizing that you already had something great.
That's exactly what happened to ShAmy. Amy may've dated other people and Sheldon may've sought out another significant other online, but their time apart just made Sheldon and Amy miss each other more.
Now that Sheldon and Amy are back together, fans can breathe a sigh of relief. However, the couple's recent reunion is only the beginning of what's to come. (Spoiler alert! Things are about to get steamy!)
Watch what happens next for ShAmy on an all-new episode of The Big Bang Theory on Thurs., Dec. 17 at 8/9c.
