Remember: everything Alhaitham [Haikaveh] says is made up.

Alhaitham hold Kaveh's waist and hand, make sure he walk properly. He sigh, rethinking why he must take Kaveh home everynight? And the most important, why he even care about his roommate? "Watch your step, or you will fall-" He doesn't even finish his words when he catch Kaveh that almost fall. "You, fool.." He choose to carry Kaveh and get inside their house as soon as possible, doesn't want to get in more trouble because of drunk Kaveh.
