Jemma's caught sight of the scars before, though usually her attention is more on how disastrously the upcoming 'sparring' session is going to go. She's not entirely surprised by the scars - after all, she pegged him as someone who'd be most comfortable in Operations quite a while ago, and they all seem to come with a vast array of scars (some more willing to show them than others).

She does take the opportunity to also change her shirt - after all, it's a very good idea and worth copying.

"That will be brilliant - they really are very well set up here."

He may, even now, lose her to that research lab.
