In the opening sequence as Jason is being wheeled down the corridor the shot shows a trail of blood dripping onto the floor but as the camera changes to show the view of the corridor the floor is spotlessly clean.
Oscar compares Kerry's blood type (AB-) to Jason's (also AB-) as a clue to their relationship. The mother contributed 1/2 of the blood type (A or B) and the father contributed the other. Oscar's correlation is nonsensical and Theo would know that.
At the end of the S2 finale, as the last person (CJ) sets the computer's automatic timer to initiate his own cryogenic sleep pod, the camera zooms in on the tablet's display which reads "COUTINUING CRYOGENIC PROCESS". Clearly someone spelled the word "Continuing" wrong.
