Okay at this point it's too old to be a spoiler but regarding Livia, I also felt this one was really one sided.
I thought she was starting to become more unhinged after the death of Rhitahtyn so Gaius probably was trying to talk with Livia one last time. Given ARR's lack of direction in voice acting and characters (I mean look at the confusion with Nael). I'm not surprised on how the scene could have been interpreted by the team/audience as "We'll bang okay"
It's funny too because looking at his VA he definitely had the chops but the voice acting in Prae is pretty goofy, so you can tell they lacked real direction at the time. Sometimes I wish they would redub those scenes if they're gonna make us watch them over and over. :P
That said, I am not really a supporter or defender of Gaius per say. Just think that particular scene is just unintentionally memeworthy.
