This Headcanon Is So Cute Omg - Tumblr Posts
Given that Noah's canonically a hacker, I can imagine he would use rubber ducking debugging.
I can see him having a rather big duck that he names Chubby Buddy. It gives him plausible deniability that the duck is a reference to anyone in particular. But yeah, when he's trying to get through a particular line of code, he imagines that he's talking to Owen. It really helps because imagining Owen forces him to explain it in the simplest way possible, which usually helps him find the problem.
Owen gets so upset when he first learns about this because he doesn't realize that Chubby Buddy is a duck. He's worried that his little buddy has another chubby buddy. When Noah does clear this up, Owen just brightens up as he realizes Noah has his own Bearry.
