They say that when somebody acts out of character it is serious business. So when Weiss let out three well-chosen expletives and tried to grind the hand written note on the beautiful stationary that gave the faintest and most modest impression of having been scented with rose water into a fine powder, her friends were duly concerned.

Sisko has always been a realist and a fighter, but his decision to bring an entire race of people into their conflict with the Dominion takes his recklessness and risk taking to a whole new level. He will single-handedly be condemning a race of people to terrible casualties to make the losses his side is taking less severe. Thatís dark territory for any character; but for Sisko (who has always been characterised as a builder of things), to see him tear a society down so brazenly is shocking. It's another example of this war pushing the characters into dark corners and forcing them to make tough calls that will relieve the situation but eat at the soul.
