lowkey... i'm coming out as an emilliam shipper. like i wouldn't ship it in any other context besides jarontiss, but honestly i think it would be cute
jj sits will down like "i'm so sorry, i think i'm a lesbian, i didn't know" and will is supportive and understanding but he assumes that he's no longer part of this relationship anymore aside from being the kids' dad but then emily is like "...actually i'm pretty sure i'm bi" so will and emily start dating, and jj and emily keep dating, and jj and will keep being amazing parents together
ooh actually emilliam also in the context of emily being unreasonably jealous of jj and will together and she just assumes she's got a crush on will bc of comphet. like she is just thirsty over him and hates seeing them together and then something clicks into place one day where she finally realizes that she has a crush on jj not will

Emily thinking that she's just jealous of Will because he's dating JJ. She obviously loves JJ, and that's the ONLY reason she's sad when she sees them kiss. She hangs out with them (pre-relationship), helps with the kids, and kind of perfectly slots into their lives. She doesn't understand why the "jealousy" doesn't go away when she starts dating JJ. One night, they're alone and he's doing dishes with his sleeves rolled up and the setting sun covers him with gold light and Emily is like, "oh my god. I'm in love with Will, too."
