10 MORE Star Trek Moments That Broke Our Hearts

6. La'an's Loneliness - Tomorrow And Tomorrow And Tomorrow

Tomorrow And Tomorrow And Tomorrow starts as a fun time-travel episode of Strange New Worlds. La'an and Kirk make a great team, stranded in Toronto, attempting to blend into a world - rather successfully, in La'an's case - that is ironically alien to them.

The comedy beats are balanced with their mission, blending so well that the almost inevitable romance brews - and works. Some people in the audience may have sensed what was coming, though Kirk's death manages to hit the right notes thanks to Paul Wesley and Christina Chong's natural chemistry.

The episode ends with a blunt order for La'an not to mention what has happened to anyone. She contacts the Kirk of her time and universe before she breaks down. The Kirk she lost was the first person with whom she truly connected, opened up to, and genuinely felt for. Seeing him so casually killed, then seeing him again with no recognition in his eyes, cut the audience as keenly as it sliced through her. 

Tears all around.
