Currently in Season 13, one of the major subplots in "NCIS: Los Angeles" involves Kensi and Deeks starting a family through adoption, and fans have seen them preparing their house for any future children. On a Reddit thread about the storyline, u/ploomyoctopus shared that they themselves are adopted and are a current foster parent, and wrote that there needs to be more positive reinforcement of this kind of family situation in media. They said, "Please, please don't handle this storyline the same way NCIS (original) did. Let them be foster parents. Let them adopt a kid. Let them struggle. Let them succeed and love their kid/s. And let them not get pregnant." 

Making reference to two children that Kensi and Deeks have considered fostering during the series, u/KeepLkngForIntllgnce replied, "I'd agree with this. I'd love to see Kensi and Deeks get custody of Pilar. That would also try to keep somehow Rosa in the background in their lives." Redditor u/InfamousClock7287 also believes in the above sentiments, and stated, "I agree with this, for once please don't do the miracle ending of Kensi falling pregnant instead do the miracle ending of a child being given their forever family." Ultimately, it seems as if "NCIS: Los Angeles" fans enjoy this story arc with Kensi and Deeks, and truly hope that the showrunners follow through with it to its completion, and not cop-out on the adoption plot by making Kensi pregnant and having them abandon their current plans.
