Juding by the cover of issue 7 he will meet up with them. And judging by this preview Kahvi will tell her story. So my guess is that Windkin, once he's heard Kahvi's story, will go off to find Venka and tell her about what happened to her mother, maybe after one of the others remembered that "Oh, yeah! That's right! Venka left because she wanted to find out what happened to her mother. Windkin, can you go find her and tell her? Also that she has a Brother. BTW; Aroree is with her, she's really sorry she kidnapped you all those years ago, don't carry a grudge."
