He does get a bit overwhelmed in the beginning, trying desperately to be able to keep up with him. It's not something he blames Gamzee for, never. Obviously it's his own failings that are the problem. So he just holds on and pulls in little gasps of air when he finds a moment to breathe.

It's far from unenjoyable though. He's young and small compared to Gamzee but he's like a puppy eager to please, wanting so much to make the older boy happy so he won't ever leave. Tavros is tired of being sad and alone, and now he finally has someone that loves him and thats all he ever really wanted.
