Zain's actions were in character-appropriate (but also indeed intended as push ball forward as well). He is conflicted by his actual loyalties as a subject of the princess/queen but also Zain having the wisdom to see that these people can be allies (albeit not subjects under his leader's reign). But also he is conflicted by his personal feelings to queen and despite that, he saw greater good in cooperating with other groups than go ruthless cutthroat tactics with them. He is neutral good after all and based on his judgement the group's efforts are genuine.<br/><br/>Ofc Zain expects some kind of penance/punishment needed later but for sake of the greater good, he is willing to endure it.
