They’d been back in time for less than a month when their father forced Klaus back into the mausoleum. But maybe this time his family can do the right thing.

How are we celebrating the not-end of the world?” “We’re thirteen, dipshit,” Diego responded, and then took a moment to process that for himself. “Fuck.” Number Five looked like he wanted to say something along the lines of “Now you know how I feel”, but he was man enough not to.
