Rodolphus frowns, thinking, drumming his fingers on the arm of the chair. "I hadn't considered that," he admits. "I'm not ready to take on the Ministry, though knowing that oaf Weasley is involved does give one hope." The point is a valid one. "Very well," he gives in. "We'll do it your way." The 'for now' is tacit.
Rodolphus takes the glasses and puts them on. He blinks and squints, trying to focus. He takes the glasses off and changes the lenses to plain glass and puts them back on. Much better. "I'll do the glamour," he says. "I'd rather. No offense to either one of you. Subject to your approval of course," he adds with some acid. "How do I look?" And if you laugh, his expression is plain, you will live to regret it. For a very long and painful time.
