Yellow. This is short.

• Harry goes to watch the Gryffindor Quidditch tryouts, in which Katie Bell is overseeing. Ron blocks all five goals, but Cormac McLaggen misses the last one for some reason.

• Harry later sees McLaggen bump into the doorframe before stumbling into the Great Hall.

• Harry, internally: Someone ought to help him.

• He doesn't.

• Slughorn asks Harry if he wants to come by his office to meet some other people in the Slug Club.

• Harry gives a very "Roonil Wazlib" type of response, which somehow works.

• (Although Luna's staring at him like his head's full of Wrackspurts.)

• First Hogsmeade weekend. Harry and Luna hang out together.

• To Harry's surprise and delight, Fred appears.

Fred: Been a while since I stepped inside Zonko's. Then I thought, why not take a look around Hogsmeade.

Harry, jokingly: Oh, so you're not here to see me? Don't let me interrupt. Come on, Luna.

• They start to walk off, stifling their laughter.

• Fred, running after them frantically: No, I'm definitely here for you! I was joking!

• Harry and Luna burst out laughing. Fred pretends to be hurt.

• Luna conveniently remembers she forgot to do something and leaves them alone.

• Harry and Fred reminisce on their date the previous year.

• I'll leave what else they did to your imaginations. (Except they don't have sex. That is the only caveat.)

• Harry later learns of Katie Bell being cursed by an object and has a horrible initial thought that Draco was behind it.

Harry, internally: No! Draco wouldn't hurt someone! He's my friend.

• But he can't put the thought out of his head completely. So he eventually speaks to his parents after another lesson with Dumbledore.

• Remus is conspicuously absent, but Sirius doesn't give an explanation. He looks worried though.

• And gets more worried still when Harry shares his fears about Draco.

Sirius: Do you have any reason to suspect him?

Harry: Well, no... But it won't leave my mind.

Sirius: Then you have a right to worry. Trust your gut instinct, Harry. I didn't and it cost us twelve years.

• Harry promises to try.
