While Rouge stayed behind with Tails, who worked in trying to find either of the hedgehog's chaos signatures, Knuckles stomped out of the room. Slamming the lab door shut in his disgruntled state. He left the lab, went past Sonic's bedroom in the hall and made his way into the kitchen to settle his anger. The echidna tried to not lose his cool. Key word, tried.
It wasn't surprising to say when he did storm away to be alone, there wasn't much he could do other than pester Tails until the kitsune could find them. He's naturally worried for his friend, before large crowds were a piece of cake for him. Or so it seemed. Knuckles could only imagine how upset Sonic must be at the moment. Sonic never really handled paparazzi or journalists that well in the past, and him being very vulnerable at the moment would definitely make Sonic feel very attacked and overwhelmed.
Knuckles pulled out a dining chair from it's place at the table roughly, the legs of the chair scraping and groaning on the floor. Taking a seat, he sighed loudly and decided to take a few deep breaths. Sonic is with Shadow right now, he should be okay right now. Knuckles is just getting too worked up. He wasn't against Sonic and Shadow being together, he just hoped Shadow didn't hurt Sonic.
Seeing that he had some time to kill, Knuckles tried to stop overthinking and worrying himself. Underneath his white glove was his wrist communicator which he revealed after pulling the glove off. The echidna decided it was about time to make a quick call to check up on the Master Emerald. A few seconds later after entering a phone number, there was a couple of seconds of ringing until somebody picked up.
"Team Chaotix at your service!"
