Priya and Leonard's relationship has gotten to a serious stage where Leonard is wearing the clothes that she picks out for him and is trying to wear contact lenses on her suggestion, even though he can't see with them on. As his serious girlfriend, Priya asks him for a big favor: to stop being friends with Penny. She feels uncomfortable having one of his ex-girlfriends be such a big part of his life. So later, when Priya asks him if he's "talked" to Penny, he doesn't tell the complete truth. How long can Leonard get away with this little white lie before he really has to make a decision between Priya and Penny, especially as Priya is thinking about relocating to southern California for good? Meanwhile, Howard performs a card trick which confounds his friends. Sheldon states that he doesn't care about the trick, but it's obvious that not knowing how the trick is done is killing him.

The technique Raj uses to shuffle the cards is called a Hindu Shuffle. See more
In the final scene of this episode, Sheldon picks the two of hearts from the deck. Raj signals the identity of the card to Howard, who then reveals it. However, you can clearly see that when Howard takes the deck out of the box (without shuffling it), the two of hearts is on the bottom of the deck and Sheldon's selected card was nowhere near the deck's bottom. Because the two of hearts is an easy card to come up with a signal for in a script, it appears that the deck is actually a specialty deck with nothing but 52 twos of hearts, which would ensure that Sheldon would pick the two of hearts from anywhere in the deck and allow Raj to send the signal, which the script called for. Such decks are readily available in magic shops or by mail order. See more
How about we still hang out, but on the down low?
Are you really that kind of guy?
No. I actually felt kind of silly just saying "on the down low."
