Gladio grinned. And showed him.

He moved his good hand to the side and in a flash of warm blue light he materialised his sword. The thing was as tall as Gladio was and nearly as wide. Black and gold and beautifully ornate, and wickedly sharp.

"When I'm fully armed, I'm pretty handy in a fight." Gladio winked, showing he was teasing and making a joke of the fact that he was currently only able to use a single arm.
