Tai nodded, and together they began to head back towards the cliffside that they had come from. He tuned out part of the conversation, not feeling too comfortable in even really discussing team roles when they weren't even sure that the four of them would be a team at all, or who the leader would be. True, it stood to reason that the four of them had been brought together by the relics with the intent of making them a team, but it wasn't set in stone by any means. If so, why would they make both pairs collect relics, rather than something simpler such as saying 'The first pair you meet you will be a team with. Go collect a relic and bring it back'? Since they hadn't, it still left open the possibility that their teammates could be other people. So, Tai would wait and see.

He stayed silent as well as Robert asked about backstories and general information, listening to Greyson without judging at this point. He did start paying attention though as it became clear that Greyson was more injured than he let on. "I know basic first aid," he confirmed when Robert asked, but it seemed the other boy didn't want assistance, instead trudging on with his sword as a crutch, something that most certainly was not good for the blade. 

So, he decided to make the general point that might have been missed in the guy's determination to not seem a burden. "So, how do you plan to scale the cliff with a broken leg by yourself," he asked Greyson in a neutral tone, making it clear that he wasn't condemning, but rather just seeking information.
