Carth had begun to wonder if the Captain had any idea about the runes but it seemed from Ash's explanation that either the Captain didn't know what the runes meant or that he did and didn't say anything for whatever the reason. Either way another mystery. Feeling eyes on him, Carth looked to Scarlet only to see that she gave him a look and guessed it was about him asking Ash about the runes. He shrugged with an innocent look figuring there had been no harm behind his question. 

"I wouldn't know. Sorry." He apologized, sadly not able to give her the information sleight have hoped. For now Carth let himself be lulled by the ride. It was nice to have such companions along. Granted he felt a little our numbered being the only male in their trio and hoped no one got the wrong idea. He would defend them with his life. "I hope Maybe we can find something on it together. It would be nice to learned something new." A grin on his face.
