Dumbledore and Harry are talking and Harry mentions a girl and says "she's just a friend...." and then they show Harry and Ginny leaning in for a kiss. Next we have Hermione smacking Harry in the library. Then it switches to a scene in a hospital (Ron's poisoning) and Lavender leans over the hospital bed and says "I happen to be his girlfriend". Then it shows a shot of Hermione looking up at the Quidditch stands, smiling really big at Ron (new shot of Ron during Quidditch shown). Next shot that I remember is back at the hospital wing and Hermione responds to Lavender with "I happen to be his friend". You see Harry, Dumbledore, Ginny, Hermione, Lavender, Ron and Snape in this scene. Maybe McGonagall too. Then Dumbledore says "Ah, to be young again..." and then you see Harry smiling really big in the common room.
