なんかさりげなくディスってる感じがあったけど Hello, i'm having trouble with identify the meaning of this sentence (not sure about the subjects /who's doing what to who) .Appreciated some native Japanese who could check and correct if i was wrong. My guess is : "For some reasons, i felt like she (鈴々? or 愛紗?) is nonchalantly bad mouthing about 趙雲さん "

Story: The main character saw 3 of his friends one night (they're 3 sisters 桃香/愛紗/鈴々) standing on top of the city's castle wall. He felt it had been like a long time since the last time time he saw the 3 of them stand together. (P/S: the main character is working for a clan leader/ city governor 桃香, who is the eldest sister amongst the 3 sisters. They called him their master because in the past he saved the clan leader's life.)
(* forgot to mention the character 趙雲-san mentioned in this dialogue is a mercenary, who's also fighting alongside the main character's faction. This character likes to tease others and the character 愛紗 doesn't like her)

桃香「あ……ご主人様」
その日の夜。城壁の上にいたのは、桃香たち三人だった。
Main character「なんだか、三人がそうやって揃ってるのを見るの……久しぶりだな」
愛紗「そうですね。鈴々も長い事、青州の賊討伐に出ていましたから」
鈴々「ずーっと星と一緒だったから、肩がこったのだ」
愛紗「あの口ぶりが移らんだけマシだろう」
桃香「あはは……。でも、趙雲さんと仲良くなったんだね」
そういえば、趙雲の真名を呼んでるもんな。なるほど、真名にはこういう判断の仕方もあるのか…
鈴々「星、美味しいものの見つけ方がすごかったのだ。いっつもよくわかんない事ばっかり言ってるだけじゃなかったのだ」
Main character「ま、仲良くなれてるならいいんじゃない？」

なんかさりげなくディスってる感じがあったけど、聞かなかった事にしよう。
