The Soldier briefly considers reminding her that this is its job, doing whatever is needed for its handlers and donating blood to techicians... but it's afraid that might lead to her attempting to argue the point, and it really wants to sit down alone now and make another little boat until it's internal static settles down to more manageable levels. So what it does is nod gravely and say, "You're welcome, Elena." It even leaves off her title this time. (Might be time for a title change, anyway.)

Besides, she looks like she feels a little better, more relaxed somehow. That's worth dealing with a few minutes of someone touching him.
