This Is How Elementary Ends For All Its Major Characters

During the three-year time jump leading into the finale, Detective Bell gets promoted to the rank of captain, taking over the precinct from Captain Gregson rather than accepting offers from the US Marshals. He's also gotten married and become a father in the past few years. While he's none too thrilled about working with Sherlock after the Reinchenbach disappearance, he's still as staunch an ally as ever for Sherlock and Joan, and it's implied in the final moments that he's about to re-hire the duo as consultants.
