Since TnT are made up of moments - I've started two threads - one when they were just friends, and this one for when they were more.
Favorite 3rd season moments of mine:
The first neuropressure scene, especially when he thinks she's coming on to him.
The horseback riding in North Star.
His arrival during Rajinn
The kiss in Similitude
The first part of the shower dream (which I think is a Harbinger flashback)
The oil painting conversation
The kiss in Home
The kiss in Bound
The hand holding in Terra Prime
- and I like to think as well that's a Harbinger flashback (instead of T'Pol wishing to take a shower with Trip in her dream).
" And then the zombie thing and you're all "DAMN!!
