I really do hope that this accident wasn't orchestrated by matthias

no, it was genuinely due to her uncle’s ignorance and carelessness. he really did mean no harm but the accident was solely on him.

as for matthias, he was going to figure out a way to make layla his no matter what, for example *spoilers from the novel,* he was always going to go ahead with his marriage to claudine but keep layla as a mistress and make her live in one his properties in the city. how he was going to do it, he still had to workshop it but with the accident, he now has the easiest blackmail he can hold over layla’s head. which is really unfortunate
