And ^^ also means that it's not Ken, or any other BK's (Bens Kids). He's probably not going to be excited about seeing his dad, especially in the past. Ben's Son was actually bery stoked about fighting with his father. Let's break it down like this:

It could be an alternative universe Ben who didn't attain the Omnitrix, though with the name Chrono Spanner (Time traveler), I doubt it.

It very likely could be Jimmy. Jimmy is known as a collecter of data as a kid, and Chrono Spanner was definitely informed about things. Also, as a kid Jimmy was a Ben 10 fan boy, similar to Spanner. This is the most likely candidate, I believe. If it is a character who has already been seen in the series, it will be Jimmy.

It might be Ben's son from the future.
