He does the thing.

Sadde closes his eyes and bites his lower lip and inhales sharply—

Theo doesn't pull away immediately.

It's about ten seconds later when he does.

—and that's when he exhales again. "I m—might need someone other th—than me to keep the time," he says in an unsteady voice.

Matt pauses and then looks at his watch. "Sure."

Theo wipes his mouth and steps back from Sadde.

Sadde licks his lips and swallows and then looks at his wrist and waits.

It takes about a minute or so for the wound to stop bleeding.

Matt reports this!

"– Again, then, and you drink the blood afterwards? We're going for the refrigerated stuff, right?"

"Yep."

So Theo bites Sadde's wrist and does the thing.

After ten seconds, he stops, grabs the blood he took out of the fridge earlier, and pours a small quantity of it out for Sadde.

Matt checks his watch again.

It takes only a few seconds to heal over.

"So the blood works in the fridge, at least for a day?"

"It… might be a good idea to see how long it lasts, if we can. As in, how long the blood still keeps you healing."

"Mmhmmm..."

Matt laughs.

"Should we maybe wait five minutes before we test it again?"

"—probably a good idea, I did not bring a change of underwear."

Matt continues laughing.

Theo opts not to say anything.

"Are you guys done there?" Willow calls from the living room.

"Temporarily!"
