They are definitely alike. Fay would probably tell a lie about her father. Being the omega of one of, if not the most brutal werewolf clans isn’t likely to win her trust points with other packs. Especially one known to put their own members into another clan just to betray them. 

She isn’t one to hate on people for not being pure of blood, but her father wouldn’t let a turned human be of a high rank. However! She’d definitely tease her for it if she saw it as a point of sensitivity for Mori.

Fay may have her own ideas, craftiness, and ability to lead. But, definitely an irresponsibility and lack of desire or connection with her own kind.

So I guess we can only work on Mori's suspicion of Fay's intention. In that case, we can say Mori actually wants to throw Fay out of the pack - simply because she doesn't trust her. Of course, she cannot get that idea pass the Carlson as he doesn't have any issue with Fay. So like you said, they would play a cat and a mouse game, with Mori trying to dig out any kind of dirt on her to prove the pack she's rotten.
