Clord theory but Tord actually kept in touch throughout the years so halfway through Clord's stay Edd gets a call from Tord like:
"Tord?? Why are you calling; did Tom lock the door from the outsude again?"
"... What? No, I just got home from work and-" Tord's voice comes through the speaker, sounding... different. Less deep, maybe? The accent isn't as thick, but that's probably just bad reception.
"What?" Edd laughs. "Tord, you can't fool me. I know you're in Tom's room right now."
Silence, some shuffling. Tord makes a noise in the back of his throat. "Oh, I get it! Haha, very funny Edd, you know I don't have the funds to get to England yet."
"Wait, wait. You're in Norway?" Edd asks. The hairs on the back of his neck prickle.
"Like..." Edd pauses, looks around. He huddles closer to the speaker and lowers his voice. "Right now..?"
"Herregud- YES, EDWARD!! I am currently sitting at my desk, in my apartment." As if to show off, several pages rustle harshly and Edd can hear the distinct sound of Tord's chair rolling backwards. "You're freaking me out."
"Okay," Edd concedes slowly. His gut twists. "But. If you're in Norway then... who's in our house..?"
