Talia observed the scene between Damon and Cassie, and she was not sure what to think. Why did Alpha Damon treat Cassie coldly? Did they have an argument? Or maybe Cassie offended him somehow.
Just based on the last minute, if Talia didn't witness the scene in the kitchen of Cassie clinging to Damon's arm, Talia would think that Damon doesn't like Cassie. But if he doesn't like her, why would he allow her to stay in the packhouse and call herself his Luna? And the way Cassie looked at Damon definitely insinuated intimacy that goes beyond holding his hand.
It didn't make sense.
This solidified Talia's opinion that Alpha Damon is extremely unstable.
In a way, it made Talia feel better because now Talia knew that she was not the only one to be treated inconsistently by Alpha Damon.
If Talia was not so terrified of him, she would recommend him to see a psychiatrist because his behavior can't be normal.
