Once he's able to leave the healer's tents, that's when he bothers to send word to folk outside Korrin and Mal, Sam and Christine that he's back proper though word has likely filtered back already given that it's Asher, he came back in a state, and that he came back with several wagons groaning with supplies for the Inquisition.

It's a young man that comes to find Kaisa first though since Asher isn't really in any condition to go to the Warden camp, not when the healers already made sure he didn't have to see Anders either. Asher was good enough to provide the name and description so there's not too much asking about, and Bronson recognises her anyway, the hound ambling over ahead of someone who could be the double of one of Zevran's kestrels.

"Asher's askin' for you," he explains, Rivaini accent still strong after years away. "Name's Nasir, he sent me to come fetch you or Christine'll have his arse, no skin off my nose if you don't but he's back at his tent and we're clearing off. Go or don't, I'm just the messenger."

Should she decide to follow Nasir back or head along after, she will indeed find Asher, still bandaged, still looking like death chewed on him and decided he was a little too tough but shit ended badly last time and well he's back. So he should probably talk to her seeing as he's not entirely a bastard.
