At first he wasn't going to do it, send a message with one of the stones. It doesn't seem real still, even though he's standing in the middle of it all. Yet maybe it's all true and if he owes anyone anything it's his mom. So he holds a stone in his palm, fingers curled around it as he thinks of her.

"I'm okay." He can't elaborate, it wouldn't make sense anyway, but maybe just hearing he's okay, however that translates to her would be enough. Just don't worry, he's fine. There's a lot of people around the river so it's not a surprise there's someone close by, but at first Dennis doesn't realize they're speaking to him.

"Hm?" He looks over, eyes widening a little, still not used to non humans yet. Some what hesitantly he'll nod, taking the offered bag.

"You ain't gonna send nothing?"
