Geordi was, of course, a trusted crewmate and friend of Picard during their time together on the Enterprise, while the all-powerful Q had a far more complicated relationship with Jean-Luc.
Star Trek: Picard Season 1 left some pretty open territory for Season 2 when it comes to its direction, so it’s not a stretch to believe Geordi La Forge or the mysterious Q could pop up anywhere.
The two had some real reality-bending battles and, if John de Lancie is headed to Season 2, I’m expecting another one to be on the way.
