aka Surviving in the Limelight
In various series with numerous characters, it's not uncommon for the story to change things up by focusing on a different character than usual.
This can be a minor character that's off on the fringe, a major character that doesn't usually get a lot of screentime compared to the usual main characters, or even a main character that isn't as emphasized as some others. This typically presents an opportunity for this character to get some backstory, undergo some nice character development, or simply give them a chance to get some nice showcasing they probably wouldn't have gotten otherwise.
For example, in Season 2's A House Divded, the Cabin Group member Nick got a lot of focus, sharing his backstory for those who didn't get some of it in the previous episode, determinately acting as a shitfaced distraction so Clementine can escape the shed they were hiding in, falling into a depression after losing Pete, and having to own up to his mistake concerning Matthew on the bridge to Walter. On a smaller scale, the finale of the Michonne DLC had featured a flashback that offered some backstory on Pete's shipmate Oak, explaining his arguments for staying as far away as possible from other survivors and showing a nicer side of him. Later in the climax episode, it is possible for Norma to shoot him if the deal goes too sour, with Oak taking the opportunity to kick her down so the other captives can escape.
