This is the third lost dog poster. Is Cruella de Vil from 101 Dalmatatians movie came alive?

First it depends on these people characteristics, and why they hate each other in the first place. If they hate each other without showing and they can feel it but still can put the fake smile to cover their canning nature. Well, the fact of she or he shows the fake smile in the normal days, which means they always think about their interest (very selfish) and they don’t want anyone as  their enemy in obvious way, so why now will show the true feelings especially she or he needs someone to entertainment her or him in these next 12 boring hours and for sure the subject they will discuss will not be about solving hunger problems around the world, strong possibility it will be about gossip. If they are reasonable people who hate each with respect, they probably sit in silence for couple of hours, reading book, maybe in somehow they will be friends if the conflict is a misunderstanding , no it’s a long shot. In general, hate itself is really has a strong meaning, yes we usually say I hate him or her but we don’t mean it. I mean until you reach the really feeling of hate which before it, you get through a lot of stages of grays’ tones of dislike or discomfort. But if you really both passed all these stages and purely hate each other, I suggest to keep pushing the red help bottom, and when you get tired just pretend fainting, yes he hates you but his best interest to keep you in one piece until the door is open especially people who know you guys know that you hate each other. Anyway, the worst scenario you will have is he will bunch you. Face it like a man (I say that to a man or a woman).
