Elisa's expression became a rapid succession of differing ones. First concern over the bruise--even if he wasn't her Goliath, then surprise at the mention of his Elisa's stomach growing (and she knew what that meant), and then a bit of confusion at the mention of being taken off active duty.

"You and her... she's... you mean... Whoah."

As far as replies go, it's not much of one, but she'd been pretty much taken by total surprise here.

Not to mention feeling the stirrings of jealousy.
