Despite Wolowitz's night out on the town last night, Howard is apparently still dating Leslie Winkle (Sara Gilbert). How do we know?
Leslie dumps Howard on the April 27th episode, "The Vegas Renormalization," prompting Raj and Leonard to go on Vegas adventure! Simon Helberg (Wolowitz) tells E! Online, "We go to help me get over a breakup. Howard gets dumped, and the guys are like, 'Let's go to Vegas!' Of course Sheldon doesn't go because he's Sheldon. He can't handle that."
Kunal Nayyar (Raj) spills a little more about the weekend saying, "A lot of hilarity ensues. We go to Vegas...and there might be hookers involved, which you always know is going to be a good time."
Meanwhile, Sheldon and Penny will both remain at home. In fact, when Sheldon locks himself out of his apartment, there's even going to be a Penny / Sheldon slumber party!
