[calls down to Alexis through air vent]
Sis! My defenses are holding!
[calls up to Finn]
You said they're art thieves, which means they're coming right to me. You need to call the police. Call Mom and Dad. Call an adult -- any adult. Do you hear me?
[Finn tries to turn on Alexis' phone, but finds it dead]
Your phone's dead. You really should get better about charging it. [Alexis sighs sheepishly] But it's cool. They think I'm a ghost.
I don't care if they think you're Santa.
Don't worry. If they get to you, we go with Plan B.
[Finn threads string through the air vent down to Alexis]
Plan B? What are you talking about Plan B?
