"What?" Shadow was alert now. "Why him?"

The Commander shrugged. "I don't know, but it's okay with him, so that's who you're going with."

The dark form finally dipped his head. "Okay. Have a good day, Commander."

And with that, Shadow left the Commander's office and just left the whole building. He was done. Sonic, of all people? His arch rival? Nope.

Shadow's cell phone suddenly buzzed. He sighed and looked at the number. It said Unknown Number.

Frowning, Shadow picked up. "Hello?"

"Hi, is this Shadow the Hedgehog?" A mainly cheerful voice sounded from the other end.

"Yeah," the ebony hedgehog told the other person. "Who is this?"

There was a moment's hesitation before the reply came. "It's Sonic the Hedgehog. The Commander gave me your number."

Shadow sighed again. "Alright. And just call me Shadow. So, you know about the mission?"

"Yup." There was another pause. "When is it?"

"I believe there's a helicopter taking us," Shadow informed Sonic. "At the G.U.N base."

"Kay. I'll be there in a flash." And Sonic hung up.

Barely five seconds passed before Sonic came running up, seeming to be slowing down. Shadow just crossed his arms and turned away. "The helipad is on the roof," he muttered.

And the two hedgies set off in silence for the helipad, where their transportation was waiting. Shadow was equipped with multiple walkie-talkies used for communicating with G.U.N, and Sonic had a backpack full of survival supplies.

Deciding to break the silence, Shadow said forcefully, "Look, I didn't want to do this. Let's just get the mission done and be over with it."

"Like I wasn't going to do that already," Sonic replied tartly. The blue speedster was already annoyed with Shadow, and they've only spent five minutes together. "I don't want to do this any more than you do."

They emerged onto the helipad and climbed into the awaiting helicopter. Sonic and Shadow sat on opposite sides of the cabin, staring out the window.

"Ready?" the pilot asked.

Shadow sighed heavily before saying, "Yup. Let's get going."
