Billy did not oversleep. In fact, he's been getting little to no sleep. Billy has been working on an old case on missing people and his team decided to put the case back in the archives. There wasn't enough evidence to solve it and he should be working on other stuff. Luckily he had the rest of the day off, so he quickly went to pick up Renee.
Yep that was Charlie in the background and he's showing off his new haircut to Renee, he's a bit self-absorbed 😂 but he's happy to see her again and is excited to show the spice festival that's in town!
