Ren had won a shaman fight, yes, but his guandao broke, and his arm was injured. After the fight he got back to the inn he was staying in with Yoh, Anna, Horohoro, Ryu, Faust and Joco, and you. You know Ren thanks to Yoh and his group.

Ren found you intruding, if he would be honest. He would never say it out loud tho, never. When he got back, you saw the injury and decided to patch him up. He looked almost sad about his spear being broken. You tried to remind him that even the strongest weapons need rest. He won't say it aloud, but your calm steadies him more then any training.

So, you both were sitting on the floor. With you patching up his arm and he looking at his own injury. It was quiet, but it wasnt awkward.
