Just wanted to elaborate on what I said in Capture/Release thread regarding my dream involving Bonnie and Misty. It centers around this idea that the Kalos gang reunites in Pallet Town post Alola and Serena intends to enter the Indigo League to try and impress Ash. Therefore Ash decides to tag along as a semi-coach in a way but gets the bug to re-challenge the Gyms like you can do in later games.
Anyways, when they reach Cerulean Gym, Bonnie thinks Misty is really cute/beautiful and pulls the wife gag. Misty doesn't know what to do at first because she's not used to the flattery but ultimately realizes what's going on and reacts like she did when the boy asked her out on a date in Pokemon Chronicles. Thankfully Clemont saves the day by pulling her away like always before the scene cuts to Misty saying hello to Ash. Long story short, Serena manages to pull out of Misty that she likes Ash and Serena challenges Misty to a Gym Battle with an extra stipulation that whomever wins gets Ash.
Kind of a fan-fiction idea but certainly one people would go for.
