Ward's wallet, something no-one had seen. Everyone wondered about it though including Fitz.
So when Fitz found a wallet lying in he lab he knew that it either belonged to Ward or Coulson, but most likely the former.
"What've you got there Fitz?" Skye asked walking into the lab.
"I think it's Ward's wallet," he replied as he opened the wallet.
"Oh my god!" Skye gasped when she saw the picture in the wallet.
There was a picture of Ward, a young girl with two different eye colours, and a younger girl.
"Ward has a family," Fitz said, gasping quietly.
