Sim love confession to T'Pol

Sim: Was there ever anything between you and Trip?
T'Pol: If you are referring to a romantic relationship... no.
Sim: The reason I ask is... well... you're all I think about, if you know what I mean. And, I'm not talking about an adolescent crush. That was... well, that was two days ago. This is much more serious, the way I feel about you. Anyway, what's driving me crazy is, I don't know if these feelings are mine... or his.
T'Pol: I can't answer that.
Sim: I didn't mean to make you feel uncomfortable.
T'Pol: I'm not uncomfortable.
Sim: I just thought I should tell you this, while I still had the chance.
