Do あなた think Byron already suspects that Ezra and Aria together???

he could have gotten a clue when Aria was going out of her way to defend 'Mr.Fitz' when her dad called him a light weight
Also he started clueing in relationship jokes like 'my daughter thinks you're pretty hot stuff!' on their way to beer, and he probably only wanted to give Ezra a 秒 chance because Aria obviously had feelings for him.
and at the bar Byron could have noticed how tense Ezra got when he brought up Aria.
