Your guardian is in the parlor with some friends. Normally you'd feel bad about interrupting their game of pinochle or whatever they're playing, but this is pretty important.
You ask him if it's possible to remotely control someone's computer to get them to install a program. He says OF COURSE. You eagerly follow up by asking whether he knows how to do it. He says he's NOT A PROGRAMMER but the LIBRARY might have some coding books. He asks if you're playing some kind of PRANK on your INTERNET FRIENDS. You tell him you're trying to SAVE THEIR LIVES. Oh, is that TODAY? he asks.
See? He knows stuff. Vision quests are legit.
