Ward, Skye, May and Amber were in the Atrium looking for their new 'bus guest. They saw door of the corridor leading to the Arena burst open and a young blonde came flying out of it, closely followed by six security guards. They were firing their guns at her. Ward wasn't worried, he knew those guns were only loaded with neuro-toxin darts. They watched as she used bars and pillars to swing around and dodge the darts. They saw her pull off a move that Ward himself had used once or twice.

She rugby tackled a pillar, but instead of hurting herself she used her momentum and the position of her arms to spin around the pillar before using her feet to kick the nearest guard in the stomach. She picked up his gun and shot the remaining five. Once all of the guards were incapacitated she spotted Ward and walked over to him.

"So why are you back here?" Ward asked, looking around the Atrium to see if anything had changed.

"I don't think Director Fury appreciated me accidentally shooting someone called Maria? At least, I think that was her name." Tilly answered, going a little red.

Ward looked sideways at his sister, eyebrows raised, a smile playing at his lips. He could hear snorts of laughter from Skye and Amber behind him. May's only reaction was in her eyes.

"You shot Maria Hill?" He asked her, stifling a laugh. Only Tilly could 'accidentally' shoot someone as important as her.

"Yeah, about this tall (she held her hand up to an approximate height), shoulder length dark hair. Hates you... Why does she hate you Grant?"

"We, Well she... It's a long story."

"That usually means that you just don't want to tell me." It was Ward's turn to blush.

Tilly turned to Skye and gave her a hug. She caught Skye in the ribs with the gun she was still holding. Ward took it off her before she 'accidentally' shot someone else.

"So, theoretical physics of the hyperthermal variety?" she asked Ward, who was picking up her bag.

"Not here." He replied, putting his arm around her and leading her to the door. The others followed. Skye saw Tilly put her hand into the back pocket of Ward's jeans and pull out what she recognised to be his flick knife. Or was it hers. She couldn't remember.

They made it back to the bus without much of an incident. They went up into the lounge and prepared to belt in while May took off. Tilly had taken her bag off Ward and was depositing it Skye's old bunk. She peeked out of the window. Most of the students who had a free were curiously watching the plane. Her phone rang. It was Harvey. She ignored the call. Since that incident with Ward, Harvey had been really nice to her and calling her non-stop. It was starting to annoy her. She had seen his true colours and had not liked them. She went back out into the lounge and took her seat.

Before long May entered the lounge.

"Cruising at 50,000 feet." She told them. They all removed their seat belts and started stretching their legs.

"So, Theoretical Physics? What do you need to know from me that these two can't figure out?" Tilly asked, nodding at Fitz and Simmons.

"The theoretical principle in question may not be theoretical anymore." Simmons answered.

"Before we start, who is Maria Hill?"

"Deputy Director of S.H.I.E.L.D. Why do you ask?" Coulson told her.

"No reason." Tilly answered, looking at the floor.
