Admittedly Carol hadn't been thinking about what Han's partner may have been doing last night or if he know where Han was. She had been a little distracted and preoccupied.

So distracted and preoccupied that she slept soundly through the night and into the morning. She woke into one of those half-awake states and glances over at the back of her partner. It's still warm and lazy and comfortable so she closes her eyes again and while is mostly awake, starts floating back to sleep.
