Troi, Ro & O'Brien. I'm not even sure how they end up on the bridge at the same time...
Troi was there to present the primary school science fair winners to Picard and, I guess, sort of stuck around even though none of the other bridge officers were there. Granted, though, the impact with the filament was inside of a turbolift ride away.
O'Brien arrived there to do a "transport simulation" according to his parting words to Keiko when he left Ten-Forward.
Ro arrived shortly after the impact after crawling out of her turbolift, presumably she was coming onto duty.
The various parings around the ship were, indeed, interesting it just would have maybe more interesting if Riker/Data and Crusher/Geordi were forced out of their respective comfort zones like Worf was, Picard was and Troi was.
But, honestly, I'm not sure what they would have entailed which may speak to the "weaknesses" of those characters. What? Have Geordi trapped in the cargobay with a cute ensign he has a crush on? Crusher stuck somewhere with someone who's a better dancer than her? Riker trapped with a subordinate, good-looking, female officer whose clothes have been ripped to shreds and there's palpable sexual tension between the two that Riker cannot act on due to him being a superior officer? Data.... Yeah I've got no "humorous" uncomfortable situation for him.
