Peiter's smile remained sympathetic. He honestly was not sure if it was just fatigue that had been keeping Tzirret so distant. It was true that they had been doing more work than usual during their searches. Not only were they on their feet walking for the majority of the day, but they were having to cut through a thicker forest than they were accustomed to. Then, after getting back to camp, they had been required to move all the way to their next campsite before finally getting to sleep. As such, it was believable that he would be fatigued, but given his present emotional desires, Peiter also found it equally likely that there could be something more. 

"Well, since we've finally found the clan, you should be able to get some rest now. As soon as you can, you should get some sleep. It might be a bit hopeful, but we may even be able to find a proper bed for you. I know myself and Sabine have been...spending a lot of time with each other as of late, but you're still our best friend. I've missed having you around with us." He commented.
