He just needed to confirm for himself that Prompto hadn't been hurt. Though oddly the giggling helped. You didn't giggle if you were mortally wounded so he laid off a bit. It was as he was beginning to pull back that he saw Prompto's eyes widen. The giggling abruptly stopped and the blonde was out of his arms faster than Gladio could thing.

By the time the Shield had managed to turn, Prompto had his sword and one of the Enemy had been skewered onto it. It's weapon dropped from lifeless fingers and Gladio reached up to gently take hold of the hilt of his sword, and the weight.

"I think... you just saved my life." Gladio really tried to temper his expression, he tried to keep it professional (despite having panicked and patted Prompto down for injuries only moments before) but it wasn't working. He looked impressed. He looked damn proud. He looked like he wanted to pin Prompto to the nearest wall and kiss him till his legs gave out.

"Takes practice." He said instead and gently took his sword back and moved to kick the trash off of the end. "Thanks, Prom. You've always had my back... And when this is over I'll thank you properly."
