When Harry looked up again, Snape was in full flight, McGonagall, Flitwick and Sprout all thundering after him: Snape hurtled through a classroom door, and moments later…
"Expelliarmus!" A voice yelled.
"What's happened, what's happened?" asked Luna.
"Avada K-!"
"Minerva, no!" A loud bang sounded from the classroom.
"Come on!" Harry said to Luna, breaking into a sprint.
Together they raced down the corridor and into the classroom, where Snape was lying on his back, wandless, with both Flitwick's and Sprout's wands firmly pointed at his heart. McGonagall looked like she had been stunted, a firm, straight line as her mouth, her wand secure in her lock-like grip.
"Slughorn had only just caught up and had the look of a man who had just run 5 kilometres without stopping. "Harry, my dear boy…"
As soon as Slughorn said 'Harry', both Flitwick and Sprout whipped around, leaving Snape unguarded./p
…Snape's POV…
Caught.
"Both Flitwick's and Sprout's wands were pointed at me, ready for any escape attempt. I looked around, my sight limited due to fact I had been knocked over when the spell had disarmed me.
"Harry, my dear boy," Slughorn began.
Both Flitwick and Sprout's heads whipped around to look at Potter.
Taking advantage of their present ignorance of me, I lunged for my wand, lying about 2 metres away from me.
"Stop!" I heard someone yell at me.
1 more metre, just one more...
There was a burst of light, and thick cords encircled my midsection, binding my arms to my side, like a spider weaving it's web around an unfortunate animal stuck in it's web.
I didn't bother hiding the fear in my eyes as Sprout pulled me up on my feet to face him. Harry Potter.
