When Janeway says "Maybe I'll stop by the pub," it has clearly been dubbed. Kate Mulgrew clearly says a word other than "pub." Actually, watching closely, she does say "pub" but her pronunciation of the word is slightly unusual - like she's trying to pronounce it in an Anglo-Irish accent, probably for effect towards the character she's speaking to.
Several crew members sustain minor injuries during a pub brawl in the holodeck. However, unless they've been specifically disabled, it's well established that the holodeck's built-in safety protocols would prevent any such injuries from occurring.
Chakotay sees Michael Sullivan after Janeway changed Sullivan's character profile. Chakotay says "I don't think we've met before." Later on the bridge Chakotay mentioned Sullivan being taller than he remembers, which would suggest they have met before.
