Who: Percy Weasley, Luna Lovegood, Fleur Weasley, Bill Weasley (NPC)
What: A nice dinner with no ulterior motives
Where: Shell Cottage

Rating: Probably "S" for "Stuffy, dry English conversation"
( If this did not get Percy relaxed enough to speak with ease around Luna, then excesses of wine were in order. )
