I do think "NON SEQUITUR" sets a precedence for Kim in "TIMELESS".
Survivor's guilt.
In "NON SEQUITUR", he felt truly bad about Tom's fate and that Danny Byrd was over there suffering instead of him.
In "TIMELESS"... well, the entire future of Kim was full of survivor's guilt and wanting to change what happened.
In a strange way, the former episode help set up, emotionally, the latter.
A very generous assessment.
