Just like that, we’re back to not knowing who’s really behind the assassination attempts – although it wouldn’t surprise me if Lalonde somehow had something to do with all of them. Nonetheless, you can ignore everything I said in my previous post, except the title and last line.
I could probably go into a detailed examination of Lalonde’s psyche and relationship with Jane, but instead I’ll just note that one could draw some parallels between Jane/Lalonde and Karkat/Sollux. The latter member of each pair warned the former member not to open their own file that they coded themselves, but the former member decided to run it anyway. If one were to take that precedent in mind, everyone involved is going to deeply regret Jane’s decision to run the file (although who knows if it’s an inevitable part of a scratched session).
Meanwhile, we now have an explanation, weird and incomplete as it may be, for why Lalonde and Strider know so much about the game. One may surmise that one reason for Strider’s weird state of awakeness may have something to do with this session eventually being joined by these kids’ own pre-Scratch counterparts; Jade already counts as the session’s pre-woken member, and this entire universe owes its existence to events within that session in the Medium.
Lalonde’s “wriggling day” reference remains unexplained, however, and her Sollux-like ~ATH coding skills could be seen as adding more fuel to that fire.
