Although he was still a lot suspicious of land folk, from the way the other merman spoke about the land man, Matt began to doubt what he knew about them. He never got in contact with one up close, but he always saw what they left behind. Some parts of the water turned pitch black because of the liquids their large vessels left, some small turtles were stuck in strange bags called - by way of rumors - plastic until they would stop breathing and die. It was a lot painful to bear, to even think of, but maybe.. just maybe, just like there are other evil mermen like Zarkon, there could be good land folk who aren't as bad as the rest.
Matt was still thinking about. Shiro believed it, and the chestnut-haired merman couldn't bear making him doubt his trust in the man. If he trusted him, then maybe he was meant to be trusted. He just hoped the merman knew what he was doing sometimes. He didn't want him to hold yet another burden on his shoulders because he didn't want to hurt others.
He opened his mouth to speak, but for a second his eyes flitted over to study Allura. Yes, in all honesty it was hard not to stare, but that wasn't why Matt looked at her for a moment. She looked concerned, more concerned than one would be taking care of injuries. Maybe she was paying attention to what they were saying after all. It made sense that she would, yet Matt didn't tread any further. He laid back as well, thinking a bit. Katie and her parents didn't deserve to think he died out there. They deserved to know he was still breathing.
But that was his own problem. Under the sea.
A human was still under less danger than merfolk were, right? They could always just up and leave the beach, yet merfolk couldn't.
"But when it comes to Katie, we're both mer. We're talking about someone else, someone different. You can't just leave him like that without a word. Even if he's.. foreign, a friend is still a friend. Zarkon wouldn't hurt a land man too, would he?"
