Wally is still in love with Holly, but right now she oscillates between being emotionally distant or outright hostile.
So here is this other girl who, during exactly this same time period, Wally is clicking with. She IS smart in an unconventional way, friendly, endearing, supportive and actually loves the "outdoors" the way Wally does.
In turn she made it clear in big bright letters that she likes him. If the kiss wasn't enough wanting to hold him high for "5 more minutes" would have done it.
So it is a difficult situation for all involved.
Wally loves Holly but Holly is currently not demonstrating she reciprocates those feelings.
Holly loves Wally but she is wrecked by past traumas that make her extremely hostile. And I would be surprised if she hasn't noticed a thing developing between Wally and the new girl, regardless of her current anguish.
Kirbee has feelings for Wally but she is aware of his own feelings for Holly, even if she only knows Holly as an angry crazy bitch who loves Wally and a casserole.
Wally and Kirbee were trying to not mention the elephant in the room but this dramatic kiss puts all the cards on the table. But nothing can happen because Wally and Kirbee won't let this escalate further while Holly is acting as a self-destructive mess. So any feelings they have will have to be bottled up or denied.
This will either end with one of them dead, with them parting ways, or in polyamory after Holly stabilizes.
But this is Endtown, so the beast of three backs is probably not how this will be resolved.
