Coulson knew the Avengers, who had reassembled after Hydra came into the open, were told by Maria Hill that S.H.I.E.L.D had been restarted. She had relayed back what they knew to Coulson. Natasha and Clint knew that Melinda May, Lance Hunter and Bobbi Morse were in on the operation, but neither knew much else. The two had been shocked hearing about several agents revealed to be Hydra. For example John Garret with his old protégée Grant Ward. They had been on several missions with the two and they were fairly decent.
Stark kept trying to find S.H.I.E.L.D and hack them but Skye was keeping him out. Cap just wanted to establish a baseline, as did Bruce. Thor wanted to meet with these allies and Clint and Natasha kept trying to find out who Fury used as his replacement but they were all getting nothing. Tony was especially frustrated someone could keep him out of the system he only knew of a few people that could match his hacking prowess.
Coulson had been trying to keep the avengers off their tails. He did not want to see what Tony and Mack could do together. Tasha and May always broke everything sparring and now Bobbi would be added into the equation. FitzSimmons and the "Science Bros" would explode the place and drive him crazy with their secret science language that no one understood. Thor was enough by himself but with Hunter goading him on he would be worse than ever. Clint would chew him out and Skye! If the two met the world would end for him. He considered both his children, but he could barely handle them by themselves together they would be a thing of terror.
So Coulson avoided letting them know he was alive, but when they discovered that Kree city and Skye unlocked powers he didn't know how to help her with he decided the Avengers needed to meet her. They were the only ones with the potential to help Skye learn to control her powers. May contacted Natasha and told her where to meet them and to bring the team. Fitz, who was taking over Skye's job because the poor girl was falling apart, found a way to get the coordinates to Stark.
The Playground had been prepared, some lanyards were made for the Avengers and everyone was getting ready for the Avengers arrival. Coulson went over some basic rules, and everything was mostly ready. Skye though did not realize the Avengers were coming. She was too terrified by her new abilities to pay attention to what was going on around her.
When the Avengers arrived at The Playground May walked out to greet them. She gave a curt nod to Natasha and Clint, before the others came to introduce themselves.
"Nice to meet you ma'am, I've wanted to establish a baseline with this new Director."
"The name is Agent May"
"Lady May, lead the way to the Director!"
"Yes, you must be Thor, Sif told us all about you."
"A friend of the Lady Sif is a friend of mine! I was not aware Sif has been on Midgard recently."
May subtly eyeing Thor's arms answered, "She came after Lorelei, who escaped when the Dark Elves invaded." Thor's face grew grim at the mention of Lorelei and decided that story was for later. Stark then went up to May, "You already know who I am, but what I want to know is who your Hacker is, not many could keep me out. S.H.I.E.L.D wasn't able to before."
"Tony that's enough! It's nice to meet you I'm Bruce Banner."
"Thank you Dr. Banner, but the hacker is one of the reasons you're here. The Director will explain though, he's looking forward to seeing you all again."
Who was this mysterious new Director and how did he know them all? There were not many who did. At that the base's doors opened and out walked a man they all considered a close friend. A close dead friend.
