Let’s talk about Kara’s reaction to Mon-El’s speech. She is listening to what he is saying, she is avoiding to look at him in the eyes because she’s trying to gather enough courage to say the words that are going to break his heart, because she knows that’s the only way he can let her go, the only way to protect him. And then we come to the second gif, Kara’s facial expression, the little grimace that she does just before interrupting him. She does not want to hurt him, but it’s the only way and I have sooooo many feelings.
