NCIS: Los Angeles season 12 episode 7 is going to be a big one for Chris O'Donnell's G. Callen. He will be having an earnest conversation with Anna Kolcheck's (Bar Paly) father, Arkady (Vyto Ruginis). It looks like he is planning to make some changes to his future -- particularly his romantic life.

Recently, CBS dropped a sneak peek of NCIS: Los Angeles season 12 episode 7 featuring Callen and Arkady having a conversation over the phone. The former scheduled a meeting with Anna's father, who is talking about other things. But, he is determined to meet with him in person.

Callen wants to see Arkady face-to-face as he wanted to discuss some personal matters. He is seemingly planning to propose to Anna and formally ask her father's permission. After everything they've been through, he is now certain to take their relationship to the next level.

Callen and Anna's romance wasn't really given a chance to progress. Hence, this is a chance for them -- especially for O'Donnell's character -- to make a huge decision about their future. It would also be interesting to see Arkady's reaction when Callen formally asks his blessing to marry Anna.

Arkady loves his daughter, so it remains to be seen what would be his reaction to the potential proposal. There is a huge possibility that he will give his blessings to them, and a father-in-law and son-in-law dynamics will be formed later on.

As for what else is coming, NCIS: Los Angeles season 12 episode 7 sees the FLETC interviewing the team members on whether or not Marty Deeks (Eric Christan Olsen) will be a good agent. This storyline could come with some awkward moments, but everyone will try their best to help him get a stamp of approval.

Based on some of the preview photos, the academy sends Defense Counterintelligence and Security Agency) Rosa Martinez (Presciliana Esparolini) to the department to interview the team. She is going to question Deeks' colleagues if he is fit for the job.

Meanwhile, the team also needs to deal with the case-of-the-week in NCIS: Los Angeles season 12 episode 7. They will be investigating the murder of a man, who's selling military information. However, this leads to the abduction of a doctor who has a cutting edge neurotechnology that could be turned into advanced weaponry.

NCIS: Los Angeles season 12 episode 7 arrives on Sunday, January 3, 2021, on CBS.
