Charlie watched as Alastor put up several privacy charms, he'd never done much of that himself - leaving it to the other Order members - Charlie rarely said anything so private that he needed to worry about it, but he understood how some people could be. And Alastor had always been one of the more paranoid people Charlie had known.
Of course this was about Callum, it really couldn't have been about anything else, but he let Alastor say what he needed to before he responded. "You're here to find out what my intentions are?" Charlie asked, arching an eyebrow at Alastor, "The way a father asks his daughter's boyfriend what his intentions are? Forgive me for being dense but that sounds a lot like prying into our relationship if you ask me."
"But, if you need help where Callum is concerned consider my door open." He told him. "And if you're planning on asking anything more you might as well take a seat." Charlie would have taken one all ready had their positions been reversed, but some people apparently needed to be invited to sit down.
