Okay but imagine Harry going to Draco for occlumency lessons because he knows Draco is good at it, like the war is over now so they should learn to get on, and he doesn’t like not being able to protect his thoughts.
Draco agrees, on the condition that Harry teaches him to cast a patronus charm.
They practice a few times a week, and Harry is shocked by how patient and gentle Draco is compared to Snape trying to teach him. Sure, he’s still snarky, and irritating, but this time it’s endearing. As time passes, they start to spend more time together outside of their private lessons, and Harry thinks he might be falling in love.
The next time Draco is teaching him, he lets him right into his mind, and at first Draco is confused, because Harry’s occlumency has been improving, but then he sees the intention and sees how Harry feels about him.
And when Draco next tries to cast a patronus, it works. And it’s with that memory in his mind, of Harry trusting him and caring, of Harry loving him.
Tom Felton: He’s a sweetheart. Everyone’s like, “Oh, he’s horrible,” but I feel really sorry for him. Harry has it easy. He has all these great influences saying, “Do this, do that, be the hero,” and Draco doesn’t even have that option. It’s, “Go and be evil or Voldemort is going to kill you,” which is pretty horrific really.But as much as he is a sweetheart, Draco’s delightfully horrible most of the times and I’ve had a lot of joy in doing that.
