First temporal dislocation due to a Kovaalan particle wakeEdit
When the Enterprise was first sent back to 2037, Aidan pursued Jennifer Crossman, a fact that only sometimes pleased her. They married on August 31, 2038, after moving in together, in September of 2037 (In Between Days:Reflections Down a Corridor, In Between Days:Entanglements).
Second temporal dislocation due to a Kovaalan particle wakeEdit
During the second temporal displacement, Jenny and Aidan got together a lot earlier, and married again, but in 2037. This time, they had a child, Steven (In Between Days:Everybody Knows This is Nowhere).
