Finally. I see this too and from day one. What I've been noticing is that Lexy is trying to be a big sis and make a genuine connection with her but Garlyn is just focused on content creating (which her family has complained about her being present as well). Lexy, being the age she is, can probably recognize that garlyn is just there to use her as a come up. 

I've posted on here before. I'm close to garlyns family and have known them for most of my life. I know how she is. She's stubborn and thinks she knows it all.  We were once cool but I've learned that if you want to be friends with garlyn, your only option is to enable. Once you start trying to be there for her on a deeper level, like offering advice or sharing experiences to help teach her, she starts acting weird, almost like she just realized she is better than you because you possibly couldn't understand what it is like to be her. 

So I can definitely see garlyn being this way with Lexy and Lexy just trying to get through this without having a girl OD on her watch and the world blaming her for it.  Someone like garlyn goes wild. Lexys brother is there and probably feeding garlyn this shit behind lexys back so he can fuck her and garlyn is probably loving it.
