What I *particularly* liked about this is that it's entirely possible to read it as deliberate on Scorpius' part, even with his POV - rather than a series of coincidences, the way events are phrased, the way Scorpius is interacting with Harry... yeah, it's very easy to read this, right from the start, as a tricky piece of manipulation. And it's left ambiguous. I like that. I like that a lot :).
