6 Satisfying Moments That Went Down On The Big Bang Theory This Season

1. Sheldon says, “I love you,” to Amy.

1. Sheldon says, “I love you,” to Amy.

After an evening plagued by panic and anxiety, Sheldon and Amy are just about to leave for prom when she says there’s something she’s been meaning to tell him. We all think we know what’s coming, but Sheldon totally comes out of nowhere to be the first to say those three special words. (Hint: “I love you.”) Understandably flustered, Amy can’t find her footing to return the sentiment, but her hyperventilation speaks volumes. 
2. Raj gets his first serious girlfriend.

2. Raj gets his first serious girlfriend.

When a couple decides whether or not to become exclusive, sometimes it can take tireless debates or negotiations. (At least, that’s been our experience, but we digress…) Thankfully, for Raj and Emily, all it took was a sweet admission that they didn’t want to date other people to take their relationship to the next level. Swoon!
3. Sheldon and Amy throw a G-rated sleepover.

3. Sheldon and Amy throw a G-rated sleepover.

In an attempt to suspend the date-night parameters of his relationship agreement with Amy, Sheldon agrees to partake in a family-friendly overnight with his bespectacled girlfriend. Though the suggestion seems completely impromptu, it’s pretty obvious Amy has been waiting nearly two years for this very moment. How else can you explain the vacuum-sealed package of slumber necessities she pulls out of nowhere? Thankfully for Amy, Sheldon sees preparedness as a turn-on.
4. Penny develops a flair for pharmaceuticals.

It might not be as glamorous as acting, but pharmaceuticals seem to be Penny’s true calling. This girl is totally crushing it at Bernadette’s company and, for the first time ever, is making major bank. Get it, Penny!
5. Sheldon and Amy agree <i>not</i> to exchange Christmas gifts, but do anyway.

5. Sheldon and Amy agree not to exchange Christmas gifts, but do anyway.

With Sheldon’s disdain for the holiday season, Shamy initially agree to not exchange presents. However, irritated by Amy’s recent PDA at a Christmas tree lot, Sheldon decides the best revenge is to give his girlfriend the most thoughtful gift possible—and then make her feel terrible for not getting him one in return. Emotional revenge wasn’t as satisfying as Sheldon hoped, though, because Amy decided to bake sweets for her sweetheart, which defied their original agreement, too. (BTW: She got the recipe from his Mee-Maw!) These two really are meant for each other. 
6. Leonard stumbles upon a scientific breakthrough.

6. Leonard stumbles upon a scientific breakthrough.

When Leonard finally strings together a concrete theory about superfluid vacuums, he can’t wait to tell Sheldon, who immediately validates his findings and encourages his friend to share his hypothesis with the world. Of course, not before Sheldon adds his own scientific two cents. Then, with the help of Sheldon’s input, Leonard’s research is greeted with huge fanfare in the quantum physics community. 

And you know what they say about the quantum physics community: If you can make it there, you can make it anywhere.
