Charlie came up a bonding exercise, basically where residents/staff members would bond with each other. They would each take turns with each other and take turns doing what they both liked/wanted to do, and it was your turn with Vaggie, And it wasn't all that bad.

Vaggie: she was teaching you how to fight with a weapon, so she tossed you an angelic harpoon. "Don't let me see weakness, that's what your opponent is looking for. Stand with caution and don't let you guard down. Ever."
