While preparing their parachutes, Jemma Simmons casually notices that Leo Fitz has no problem with the straps "this time," to which Fitz replies that they have come a long way. They are talking about FZZT (2013) when Fitz attempts to rescue Simmons who jumped out of the Bus but fails to strap his parachute, forcing Grant Ward to go instead. It is the second time this event is mentioned in Season Five.
