"Don't try to sit in that chair." Relena called it out form the other room. Duo was confused wondering how she even knew which chair he was looking at.

"Huh?" Duo asked. Suddenly there was blur, and a large dog sitting at full attention and in guard mode growling at him.

"Heero's chair, to be clear: even I am not allowed to sit in it. Zero is extremely protective."  Relena's skills were impressive. She managed to explain that without missing a beat and making it sound perfectly ordinary.  "Call it animal instinct, but he won't let anyone else touch the chair."

TheChair(tm) didn't quite "match" the room if you were in to that thing. It was more simple, but also more comfortable looking. It was the clear result of some sort of compromise along the lines: she could decided every other thing about the room, he got 1 chair.

When Relena joined him in the room with the tea trey in hand, Zero gave out a small woof. "Your a good boy Zero, no one is trying to take the chair. Heero will be joining us soon." Zero suddenly perked, then his tail started to thwump against the chair when the front door opened.  He didn't move from the chair but kept wiggling in different positions trying for a maximum ability to see down the hall.

Heero came in to the living room, now Zero was practically crying for attention.  Heero stopped and gave him a few pets. "Good boy, off."  Zero happily jumped down and then curled up right next to the chair as close as he could get. Heero sat down and gave Duo a polite wave.

Relena brought over a tea cup for Heero. This time Zero remained calm. She leaned over and pet the dog who happily wagged his tail, everything was clearly right in his world.
