Graham, The Doctor and others in “The Haunting of Villa Diodati”

You saved Shelley, but what does that mean for the future?

It means I put it in the gravest danger.

Please, tell me that was part of the plan.

Yes. A last-minute, imperfect, all-I've-got plan. Saving Shelley was step one.

What's step two?

Fix the mess I created in step one.
