Perez and girlfriend have a security camera set up at their place, mostly to keep tabs on Nina while they're out. It's programmed to alert them if it detects motion after midnight. And on this particular night, that's exactly what it did.
"I got a intruder notification while I was away, getting ready to sleep," Perez told The Dodo.
Turns out, there was no intruder. The camera was triggered by Perez's girlfriend getting home late from work. And as he laid there in some unfamiliar bed, quietly pining for his loved ones back home — imagining them doing the same — Perez accessed the security footage on his phone and learned the truth.
Basically, a dance party was underway in his absence.
