Harry apparated to the Burrow with a pop. He didn't know if being in the only place he thought of as home would have a good or bad effect on the potion, bur he didn't give a damn, his family was hurting.
He saw Ginny standing in Draco's arms and he fought not to look away. Draco had done more for the family then he had at this point and that hurt, but he couldn't touch her anyway so it wouldn't have done a lot of good.
He gave Draco a stiff nod and mentioned he was going in side. He would see what he could do for the man that was like a father to him.
