this is his son - he literally thinks of jake as a son. and that son, whom he’s mentored and nurtured for four full seasons, through defiance over ties and even a stint in witness protection, has been unfairly convicted of a crime holt *knows* he didn’t commit because he was trying to help him make the bust. now that son, a damn good cop according to everyone who knows him, is going to prison. his prize mentee is in love with his son, and they’ve just been sentenced to a 15 year separation. and holt has to watch, knowing that the police system he fought to make better is still deeply flawed and having to come to terms with the fact that as a cop, he just couldn’t do enough to stop this.
What she means:
Lance McClain was clearly set up to be a major protagonist, if not THE protagonist of the show Voltron: Legendary Defender, and yet we barely see any of him in Season 2. He had only two action scenes in Season 2, and other than those, we only see him lounging around, or not at all. But Lance is clearly loved by the fandom and we, collectively, should adopt him, and give him the love and care he deserves.
