When Velcro stands, head cocked to one side, it gets Sebastian's attention and he slips a bit of paper into his book to mark the page before reaching down to ruffle the dog's ears.

When he looks up, Severus ought to be able to see his face clearly and if he's observant, he can notice the tinted contacts and just a bit of make-up used to hide something behind the messy fringe of his hair. Save the missing fingertips, most of the obvious damage to his body has been done through magic and, at times, might remind him of the sort of injuries Moody might've been prone to.
