Good point raised there. also makes me wonder if back when younger el didn’t know about her mum, what did memory she think of to get strength to cast henry into the upside down. bc how i understand it is that the nina flashback memories took place before s2 and now in s4 she knows about her mum. bc she only got to know that her mum got into the catatonic state in s2 and didn’t have any prior memories of her right? (pls correct me if i’m wrong 😭)
Oo and also i think that during very first nina flashback memories she didn’t know what was happening bc she got knocked out by brenner right and then she figures out that she’s in a memory and after, they eventually explained to her what they’re doing so she understood what was happening
