Look, I need to preface this comment to say that I do love this arc. It's very cute, there's lots of smiles and closeness and encouragement... BUT ... it is kinda, ruining the already established story?
There's no way, after spending this much time together, going to classes, and all this other stuff, that Elsa doesn't recognise the name "Smollet" when she starts going to the school?
Unless,
1. The thing that Evie is changing in the timeline is that Elsa immediately remembers her and pursues her when they meet again (unlikely, because didn't the bracelet react to Evie trying to tell Elsa her name when they first met?)
or
2. Elsa gets her memories wiped. But, really specifically, like, only of Evie's name. She remembers the promise vividly and what Evie looks like, so this is kind of doubtful?
So ... has the author given up on making it all join up together? It's not that huge of an issue if they don't, plotholes schmotholes. But it is making the chapters less enjoyable as all this plays out in the back of my mind.
