NCIS: Los Angeles season 12 is coming to CBS, though viewers may need to wait for a while as it may not be coming anytime soon due to the current global health crisis. But once it arrives, the series will further continue the lives of the characters, such as LL Cool J's Sam Hanna.

Sam is one of the essential characters in the series, and it looks like more stories are coming for him in NCIS: Los Angeles season 12. The character is a leader, a fighter, and has gone through a lot over the past years. His story will further continue moving forward.

NCIS: Los Angeles season 12 may deliver more Argento' storyline, which hugely involves Sam. In the season 11 finale, the latter was at the center of everything and it looks like what happened here sets up more stories down the road.

Argento is a compelling villain and he's capable of causing chaos, thanks to his political connections. Moving forward, Sam and Callen need to deal with him and stop him from bringing more troubles to the team. There are only a few details when comes to Argento and we'll likely learn more about him later on.

Sam and Katherine's relationship may be also explored in NCIS: Los Angeles season 12. It's still uncertain what the long-term future holds for them, but there's more to explore in their story. Both of them are different in a lot of ways, yet this could make them attracted to each other at some point.

However, this may likely take some time, given that Sam has just lost Michelle. Apart from his potential romance, it would also be nice to see the series bringing stories about his family. They are part of who is, but it's not explored all that much.

This storyline could also offer more insights into the lives of his kids, as well as how Sam is as a parent. When it comes to his professional life, there could be potential changes in his job. It's still unknown how long will Hetty be in charge of the team, but Sam and Callen will possibly work as mentors to others.

NCIS: Los Angeles season 12 will also bring more Sam and Callen moments. Their dynamics is one of the interesting parts of the series, as they bring fun, serious, and more action moments. These two are essential parts of the show and it would be nice to see them teaming up in more missions.
