OMIGOD! What fun! She gets to have her late and wonderful, lovable husband still in her life, and Snape in the sack with her, while Christopher approves. Talk about having and eating cake! Anna's a lucky woman!

Well, as you can probably surmise, Christopher was married before (and widowed) so he understands what Anna has gone thru since his death and knows that love can happen again when you least expect it. He's a pretty cool guy, Christopher and he does make friends with the other portraits, being partial to Violet, the Fat Lady's friend. More than that...?????
HE!HE!HE!
