10 Most Emotional Big Bang Theory Moments

10. Sheldon's Two Loves

By season seven, Sheldon and Amy were still rarely intimate in their relationship. Despite Amy's constant attempts at trying to get Sheldon out of his comfort zone, he remained as stubborn as ever for the most part. They held hands and had a few hugs, most of them awkward, but nothing beyond that.

For Valentine's Day one year, Amy had booked a table aboard a vintage train alongside Howard and Bernadette, with the hope that it would help Sheldon become more romantic. Unluckily for her, there was another train fanatic onboard that day, a man who Sheldon instantly befriended. This caused Bernadette to show her more aggressive side towards Sheldon, angered at him not spending the annual day of love with his girlfriend.

Hearing this, Sheldon began being sarcastically romantic, drinking wine and gazing into Amy's eyes. Afterwards, he kissed her, a moment that began as uncomfortable to watch due to the awkwardness, but it transitioned into a truly romantic moment between the pair. That's something we can't always say regarding ShAmy.

Even though the kiss began in awkward fashion, the fact that it ended with Sheldon realising he enjoyed kissing Amy ensured it ended up on the romantic end of the spectrum.
