Ehsan is just being ehsan-supportive and loyal. To both his friends. He is not picking sides, because there are no sides to pick. There is only one side Team Kaviaan. So he is neither team Viaan nor team katha, and instead of pitting them against each other he is supporting them both. I think he's being very balanced and unbiased, and as always this centered view allows him to see reason. Him and katha have not had any interaction yet, and I think when they finally get a chance to meet Ehsan will, in his usual calm, non-judgemental way, nudge katha in the right direction.
Vanya is completely supporting her brother which is also understandable. Her relationship with katha was fairly new, and mostly by viaan's association. She wouldn't have been close to her if Viaan and katha weren't together. She's also young and not much privy to their relationship dynamics. Ehsan shared an individual relationship with katha outside of Viaan's relationship. In fact Viaan got added in the mix later. Ehsan was her friend and confidant first. He liked her and cared for her. And then supported and rooted for both his friends. He's just being consistent with his character.
