Bobbi beating up some bros who were watching Clint's apartment building in Hawkeye #9. The real kicker? She was there to get his signature to finalise their divorce. They might not be together, but Bobbi's still there to help.
She's later mentioned in Hawkeye #11, in an unknown conversation from Lucky's POV, possibly being able to corroborate Clint's wereabouts at the time of Grills' murder.
