Harry was a young man who had very few options when it came to family, or links to his past, and had accepted Remus because of that. And Dumbledore had been an extraordinary man with his own scarred past. They were exceptions. Tonks had no real reason to make exceptions, they way they had done. She'd simply done it. He'd never understood why, but he appreciated it, nonetheless. "I could let you paint the red letter on me, to make it even. Or start wearing a false belly under my jumpers. Though that may earn me some funny looks," he offered with a slight smile.
"They'll just care about you, Tonks, and want to help, I'm sure." Tonks' parents were good people. Andromeda always had been, unlike her sisters. OR Bellatrix, at least. Narcissa had her redeeming qualities. "And yes, I'd like to come with you and help. And it's not pointless - though keeping him here may be for the best, anyway. Hogwarts is still a good deal safer than most other places, these days."
