Your familiar seems hostile to all creatures other than you, hissing at them if they get too near. When you Cast or Sustain a hex, your familiar can curse a creature within 15 feet of it, prolonging the duration of any negative conditions affecting it by 1 round. This is a curse effect. This prolongs only conditions with a timed duration (such as “1 round” or “until the end of your next turn”) and doesn't prevent conditions from being removed by other means.
First of all, what is a negative condition. Note that the word Condition is not capitalized meaning that it does not necessarily reference conditions like Stupefied or Clumsy but could be applied on a much wider scale
"This prolongs only conditions with a timed duration" does the timer need to be on the condition itself or does it also apply to spells that inflict conditions that have a duration? What about Sustained spells? The core rules specifically lists Sustained spells as having a duration of 1 round https://2e.aonprd.com/Rules.aspx?ID=2242
If the extension only applies to conditions that have a specific duration and not to spells that inflict the condition for a given duration, what about https://2e.aonprd.com/Spells.aspx?ID=1500 ? The spell lists the condition duration right next to the condition, but the Duration says 1 or more rounds (see below)
