While talking about NCIS, Wilmer Valderrama teased that things will change in the new chapter. He said:

"Look, every couple of years, you guys know 'NCIS' has to make sure you're watching. So we shake up the TV a little bit and we listen [to fans]"

He continued:

"So if you ask me to speculate, I think there's a major, major shakeup happening."

The exact plot details for NCIS Season 24 remain under wraps, but this aligns with the Season 23 finale cliffhanger (gunshot in an alley involving Torres and McGee’s son Mateo) and the leadership vacuum left by Vance.
