Actually I wanna see Isabeau be more jealous platonically. Make him very defensive over Mirabelle or vy for Odile's attention and approval. I wanna see him visibly droop when Bonnie goes to give him a hug and runs past him at the last second to give it to Siffrin. Have him get all starry eyed when Petronille admits both of them are friends now.
And be so so upset when anyone divides their attention anywhere else outside their friend group. Inhales and sighs, looks away and twiddles his thumbs to not be vocal about it. Trying so hard to keep it in when everyone can tell Isabeau wants their attention.
