Inspect isn't the term exactly. Well, Bruce does spend a few seconds looking it over, but it's just... a hand. Green, small, but a hand nonetheless. He lifts up his own hand and holds it next to hers. Her fingers are much tinier than his, but he doesn't point that out - he goes with something else instead.

"We look alike."

In one other way she wouldn't know about too; but he keeps that tiny detail to himself.
