You know, after the credits for a few seconds.
We track Older Spock going back to where ever he goes back to and Shatner steps out of the shadows so to speak.
The thing is, nobody has to explain how/why Kirk is alive. That's the damn fun part. How was he resurrected? Was it like the Shatner books? Who knows? It's just for the fans. It won't ruin the flow of the movie that way.
Plus of course they get repeat viewers for those who left too soon.
