Jealousy
Colin: *comes over with a wide smile* "Hi Harry!"
Harry: *uncomfortable* "Uh...hi..."
Ginny: *is sitting nearby, squinting* "Is it just me, or are they close?"
Tom: *hissing* "KIll him!"
Ginny: "I just remembered that I have a super-important thing to do..."
Harry: "You do that. Meanwhile, I have Quidditch Practice."
Colin: "And I'll go with you for moral support..."
Ginny: "Moral support...sureeee..."
Tom: "Sadly, we can't kill him yet. Too many people will be watching. But we can do so at night."
Ginny: "I think I will go watch."
Lockhart: "So will I for no adequately explained reason."
*Harry ends up with a broken arm*
Colin: "Let me take a photo of you when you're vulnerable, as fanboys do!"
Lockhart: "I'll attempt to heal this despite not having any medical degree!"
Ginny: *adds them both to kill list*
Tom: *hisses in encouragement*
Ginny: *goes to the second floor, yanking Mrs. Norris' tail as she passes*
Mrs. Norris: "You're being disrespectful."
Ginny: "And you aren't supposed to be able to talk. Or move."
Mrs. Norris: "We're just going to ignore that."
Ginny: "Whatever." *enters the bathroom and starts to hiss*
Basilisk: *comes up* "You called?"
Ginny: "We're going after Creevey and Lockhart."
Basilisk: "Sweet!"
Ginny: *climbs onto her back* "Onward!"
*Colin is sneaking through the corridor leading to the hospital wing, when Ginny and the Basilisk appear out of nowhere*
Ginny: "You are going to humiliate him again, aren't you? Well, not on my watch!"
Basilisk: *stares him down*
Colin: *uses the camera as a shield, but his body goes rigid and he falls down with a dull thud.*
Ginny: "One problem solved." *listens* "I hear footsteps. Let's disappear." *Ginny and the Basilisk disappear inside a pipe*
McGonagall and Snape: *arrive* "Who could have done this?"
Dumbledore: *arrives* "Hospital wing is nearby. We'll take him there and hope for the best. The Mandrakes should be mature enough soon..."
Ginny: *is listening* "Shouldn't we get rid of the Mandrakes too?"
Tom: "That is a good idea, yes. Why didn't I think of that?"
Ginny: "Your knowledge is lacking..."
Tom: "And that's why I have you."
