Falling in love is kind of exhausting isn't it? 'Do I call her?' How often?' How many emails (texts) should I write?' How long until I answer?' Did he touch me by accident or on purpose?' Should I wear this or that?'
Add to the equation the fact that we never mean what we say or say what we mean and it's a wander we manage to make it happen :) Well, in my old age I've learned that directness is the best policy and I'm stopping now becasue this digressing has nothing to do with your story :)
My point is that Draco and Hermione are walking in circles around each other. Hermione must have a powerful antenna to pick up on Theo's inner issues. I can tell you that it's almost impossible to be that good at reading people. Case in point: a student at my school, quiet as can be, reserved, comes to resource room to work. Talks to me for the first time and even attempts a smile. I shook my head at the gesture and made nothing of it other than thinking, 'isn't it nice? He is finally feeling comfortable with me' Later than afternoon, after school, he jumps off the balcony while visiting his grandmother and kills himself. We, the staff saw nothing, heard nothing, sensed nothing which could have alerted us of what was going on with him. I have known two more people who have killed themselves and is the same story.
Might be that Hermione, having lived with someone who had killed himself is more in tune with what the rest can't see. I'm sure Theo didn't 'die', he did himself in.
I find this Draco likeable. He isn't afraid of Hermione, of challenging her or of backing down when is needed. Saving the differences he behaves like Harry did in the books but not as nice as Harry did. And before this turns into a bloody essay, I'm stopping.
But I love your essays. I'll give you an A plus on this one. And the fact that you picked up, like Hermione did, about Theo this early in the story was a bit uncanny.
