Well, as someone who didn't read comics, Luke was under the impression that it was Alfred who made Batman's equipment.
Luke was quite confident in his capability.
After all, he could now jump from the third floor of a building without getting hurt.
All he needed to do was streamline certain movements so that his body could take the impact.
He continued working late into the night. Selina checked on him at midnight, but got bored and left. She wasn't interested in crafting.
Luke took a shower and went to bed at two in the morning.
On January 4, when most people were still enjoying their break, Luke returned to work with Elsa.
Elsa greeted Dustin and gave him some gifts she got in Miami, which weren't very expensive but quite thoughtful.
Then, Elsa and Luke left the police department.
Luke asked, "What's the case this time?"
Driving the car, Elsa said, "This case has to be kept confidential."
