Tavrose freezes, looking nervous near the point of fear, put on the spot with what is for him something that feels like a life changing question. It isn't just a matter of coming out, its changing his relationship with Gamzee forever. As it is they may never be able to go back to the way things were, but there's still a chance?

If he says yes and something goes wrong he'll lose him forever and he doesn't think he can handle being that alone.

But what if it doesn't go wrong? What if... what if...

It takes so long for him to respond it starts to seem like he just isn't going to answer the question. He still can't seem to get the words to come on their own, but he finally just reaches out and takes Gamzee's hand, holding on tightly.
