Kaidan leaned into Shepard, a chuckle escaping his lips at the look on Garrus' face. It seems he had his hands full. This woman was going to fit in well with their little group, and Kaidan was happy for Garrus on that end. Maybe she would loosen him up a little more too.
Marguerite smirked at Shepard's words and then turned back to flashed Garrus a wink. "Oh don't worry he's already learned a few things. He knows all the right places to touch a lady" she added a little taunting grin still on her lips.
