I wouldn’t put it past the franchise to have that actually be true. That would be funny though, I would love to see that character interaction.
They worked in the same hospital! They both could have done what they showed Dr. Gordon doing to assist John with the medical aspects. Maybe that's how they intend to tie Logan into things if they proceed instead of dragging Dr. Gordon back into it (I don't think Cary Elwes is interested in coming back anyway)
