Colin- Draco is touched about how much trouble Colin went to for him. Since Colin knows him so well, he would have easily seen that Draco was overwhelmed/shocked, but also very grateful. Colin would be one of the few who glimpses watery eyes.
Lilu- He says she is probably just tired of him doing the chores BADLY. She also gets a big hug because he loves her.
Charlie- He is super excited about the baby so those gifts are adorable and awesome! He would put on the shirt.
Teddy- He is really pleased to have Teddy here and is tickled by the lightsaber things he does not understand. They need to watch the films together (again).
