Oliver paused mid-dunk with the next part of his sandwich, realized he was probably staring a bit and that might make Marco think he was doing something wrong, then managed to restart himself.

"You can always try and see how you feel. And if it turns out you aren't as ready as you want to be, you can always come back. That's always an option."
