He realises draco is the baby after he sees similar pale silver hair, grey eyes and a black mark where the where the dark mark should have been. He freezes, and calls for harry. Harry is a healer. He sees ron rush in st mungo's with a baby and take him to a private room. Ron tells him everything. Harry freezes, millions of emotions running through his mind while listening to ron and looking at the child. Then, later, he goes home to Ginny and tells her everything. Ginny and harry can't have a baby after Ginny got hit by a stray curse during the war. Ginny tells harry what if this is fate, and if others know who that baby is, no one would want a death eaters even if he's a child. So, with a heavy heart, harry and Ginny decide to blood adoot the baby. Ron and Hermione is also present during the ritual. The ritual proceeds, binding their magic together. .
