As he laid down, he closed his eyes only slightly, back leaned against the bed. He let out a soft, relieved huff, glad to have been able to both survive and come here on his own. He felt shuffling right next to his head, and soon a nice, comforting scent entered his nose. It was - no doubt - caused by some of the rocks and anemones the mermaid had with her. It wasn't a popular healing method merfolk usually use, but he was still familiar with its effects. Slowly, it began to feel like he had no cares at all. Like he was aimlessly floating away, lulled by the sounds of the water. 

But although it was a comfortable feeling, it didn't last too long. Soon Matt heard what the mermaid beside him had to say as she settled on the bed, tucking him in safe and sound. He wished that were the case. 
So, not only was this mermaid familiar with land men, she even went so far as to say she had human friends. It didn't seem like she was too different from Shiro in that case, and he began to understand why she offered to help. Perhaps there are nice land men out there who aren't out to hurt them. 

"For years, huh?" He asked drowsily, but still trying to focus. "You seem like very good friends. I just hope Shiro's friend is as nice as your friend is.." his voice trailed off sadly, only slightly listening to the names the merman said. Adam, he knew. Matt was his name. Perhaps this Keith - if he even caught the name correctly - was the human? He could barely know, because soon his eyes began to droop on their own. "Thank you. For offering to help and all." A smile was directed to the mermaid, who was the last person he saw before he began to lose consciousness.
