T-Rex: Batman, who was the world's greatest detective on account of how nobody could detect better than him, scowled.
T-Rex: He'd just detected his LEAST favourite thing...

T-Rex: ...A CRIME!

T-Rex: And at the scene of said crime was a man dressed like Sherlock Holmes, which made sense because he WAS Sherlock Holmes. YES: these two detectives were finally going to meet!!
Dromiceiomimus: Do they get along?
T-Rex: HAH! Not hardly!!

Utahraptor: Because they both think they're the world's greatest detective?
T-Rex: Nah, that part's fine.

T-Rex: But on a dinner date, they discover that Sherlock LOVES crimes, because he loves solving puzzles! Meanwhile Batman HATES crimes, because his parents died when a friggin' crime happened on them! So as you can see, they're on opposite sides of the crime question.
Utahraptor: Sorry, wait, they're DATING??

T-Rex: ???
T-Rex: I thought everyone knew??
