When Hardison tells her that they're more than a team, she almost bolts then and there. Even being on a team after all this time is difficult, but the idea of having another family, another group of people that she could potentially lose, that was worse.

So when he says again that they're a team, she takes it a step further and repeats his own words back to him.
"We're a little more than that."
