A regular means they will be part of the main plot of the season. Jack was the center of Season 13 so that’s why Alex became a regular. The numbers for any regulars but J2M are usually low though.

If Alex is still a regular in Season 14 (which I’m very sure he will), he’s going to appear in less than 10 episodes for sure.
