Lucky for you, Filch had already changed direction to the other side of the castle by the time you finished descending the stairs. The parting was not emotional or interesting, with a "goodbye" each of you went a different way down the hall. After all, that's what you and Malfoy always did, ignored each other when you could. Maybe it was really just a misunderstanding, soulmates were supposed to attract each other, not repel, you thought as you walked to the gardens.
