Startled at being forcibly brought to the ruins and reminded of similar happening at Halloween, Andromeda is very careful to not stray too close to the borders of the event. She has two and a half glasses of wine because wine!, at last, but doesn't drink enough to get drunk. Definitely not as much as the last time she had wine, in the bar with Bellatrix and Narcissa.
When a group of people depart for the village, she will go with them. There's safety in numbers, right?
