They’re expecting to see eachother, especially Zeno and Jaeha who have been used thus far know they’ll be going up against Kouka’s army -which will have the other because obviously they’re trying to rescue Yona, Jaeha, Zeno and Yoon. In 168 Jaeha basically says “来たね” to Kija, which basically means “You came” but in a more “I was expecting this” way, right before he kicks Kija.

I'm scared....if they fight each outer without knowing their there I don't know what I'll do
