Good question. Some people tag passages with different colors for reference, but idk if it was supposed to have a specific meaning for Luke's brother. I think I lost focus on Luke Cage towards the end with his brother and a lot of stuff stopped making sense to me, but that might have only been me. It couldn't hold my concentration so I still have a lot of questions I never bothered to ask. I wonder how much of Defenders will actually affect LC s2.
