One noticeable problem with this episode when rewatching it is how out of character Rom is. I suppose you could make the argument that Rom evolved over time due to his interactions with Starfleet types, but it still seems like a stretch that Rom would be willing to kill Quark when such an integral part of his character later on is how important family is to him. \
I totally buy the Rom thing, I think back to Necessary Evil when Rom was upset about Quark but at the same time was excited about inheriting the bar. Maybe that's why Rom is always so nervous he's always so conflicted.
