That's right, the science wonder twins may broach the topic of Fitz's (Iain De Caestecker) underwater heroics during "...Ye Who Enter Here."

"The duo look poised to finally discuss the reason behind Fitz's selfless act from the season 1 finale during Tuesday's episode, but Fitz will make a surprising new declaration that could shake up the team," Entertainment Weekly announced. "You might want to have tissues handy."

"That machine is so painful and I don't wish it on anybody, but if there's anything to be done to get Fitz back to his former intellectual glory, I think Coulson would risk anything," Gregg told Entertainment Weekly.
