That year, when Kyle Riker came aboard the Enterprise-D to brief his son about the USS Aries, Boliska greeted Riker with a handshake near a table of two other female acquaintance in Ten Forward. Moments later Riker spotted Katherine Pulaski and left his three acquaintances to greet his old friend. 

Boliska manned the helm on the bridge when the Enterprise-D made First Contact with the Borg the same year. 

He was one of the crewmembers selected by Commander Riker to serve under his command aboard the USS Hathaway in a Starfleet battle simulation.
