Under slightly different circumstances, would any of the other alphas have bonded with O!Sky? What circumstances would have to happen to cause that for each of them?
Oooo what a good ask to chew on, Ace. The biggest and maybe only reason for Time to bond with Sky in the beginning is to break his bond to Demise--whatever that actually means this far out from Sky's imprisonment. The other alphas can't physically do that (for reasons not revealed but I bet you can guess), so orchestrating a bond between him and the others is a challenge to consider.
Legend - This is fun to contemplate. Because in his own time, Legend is not of the stature or status to be bonding to an omega. He's not even totally sure how to do it. If this was to happen at all, it would have to be initiated by Sky, which I can only picture being a hormonal thing. It would be hard to Legend to say 'no' with all those hormones and scent signals and physical signals, but like. The post-nut clarity is going to be ugly for both of them.
Warriors - HOOOOO BOY this one. This one might be the least likely. Both of them have had terrible experiences being bonded to another in the past. Perhaps rather than bonding, Warriors would be the one to point out to Sky that bonds fade, that the thread is broken, that Demise is dead and the only thing tethering Sky to him at this stage is his own heart. He needs to let it go.
Twilight - Yeaaaaah Twi would. Knowing that it would help Sky through his anguish, he wouldn't think twice. He's like Time in that way. And because he has baggage related to feeling unwelcome in his own era, he would be happy serving Sky for the rest of his life. He wouldn't go back to Ordon. If he wasn't such a lamb and would have accepted an invitation into Wild's house during the events of Trust Us, Sky's bond with Time might not have happened.
