Reiner comes up for air just in time to get a mouthful of water. He coughs a little, but that coughing very quickly turns into laughter. Not the chuckles he usually allows, but something more boisterous.

Like Bertholdt, Reiner's guard is down. And seeing Bertholdt's guard down as well just makes Reiner smiles all the wider.

"There are definitely rules!" he exclaims as he splashes his partner again.

Meanwhile, the water fight that had been starting up is drawing nearer, sneaking up on the two Warriors blissfully playing.
