Sennet´s sisters (and also brothers https://www.furaffinity.net/view/54731660/ ) gets along great with Erik, but no one so much as Killyiki: https://www.furaffinity.net/view/45592810/ she really appreciates a lot Erik, first by what he did for her brother and later because she liked his personality and kindess. Also likes how fluffy he is at contact, even for a hare, and of course as good hare she also finds interesting his long snout https://www.furaffinity.net/view/45825644/ and tail, ("foxes are so different!") situation that she uses to prank him quite often. Erik finds that childish and silly...and funny, so he follows the joke and retaliates in the same way that he does with Sennet: calling her "bunny" XD The Harkonnens HATES being called bunny, they are proud hares, but accepts it well from Erik because is a family friend and he is just mocking them. Plus always can work in team to pounce him and tickle his paws until he surrenders, things that happends in a few SECONDS XD
