Her tears pained him to see, and he wanted to reach out. Of course that was impossible, so instead he did the only thing he could to reassure her. He lied.
'Of course I am well, my love. Someone like me does not fall ill.'
He smiled at her, fighting the urge to scratch...well anything really as the marks were really starting to bother him at the moment. Instead he focused on her words. 'I trust you with Severus,' he said softly. 'I am sure you'll handle him expertly and will convince him properly that the child should not be around the manor.'
'If not there are of course other methods of dealing with him.' Killing him being high on that list.
