Hi Morgana,
Thanks for the FDK!
If you think back … way back … to Volume 2 “Borrowed Time” – after the McVey style terrorists were rounded up, Lois and Clark went to ‘their’ island hideaway for their vacation.
That trip was where Jon was conceived. This is the explanation of how that hideaway came into being and why it was needed.
That is just one more example of how these stories are intertwined.
