Spencer and you had a one night stand after you both got drunk and sad. You accidentally got pregnant with twins t/1 and t/2 (twin one and twin two, make your own names) and he doesnt know about them. You both are still working together at the BAU and your car broke down at the end if the day, you asked Spencer to drop you off at your house and he agreed. You guys start driving and talking about the most recent case.
