Maybe this interview they just acted like they were halfway decent to eachother. But it seems like most news that comes from the two are about one being an asshole, or the other not thrilled with performance on the track.
Monza for instance, from what I heard Vettel was livid that Kimi came in and took pole and bumped him back. There are loads of other examples I’ve seen about them absolutely hating eachother on the track at least.
