In regards to combat and such, we follow normal rules.
To attempt difficult maneuvers, like Kiph penetrating your mind or Curie turning your equipment against you, they would need to make successful mind probe and hack rolls.
Strictly speaking, Curie might have needed a skill roll to listen in on your little conversation, but in the interest of player survival and party cohesion I let it pass.
Offensive / threatening maneuvers will ALWAYS require a skill roll.
Persuasion is one honest exemption from the "player is a normal world character" rule.
Unless implanted with mind probe suggestions or drug forced or implanted with cerebral devices, a character is always free to follow his own agenda.
So, you cannot "charm" a character and say: "I sex you. We do it doggy style on the sofa"
You could implant the other character with a kama sutra implant and then operate sexual hormone stimulants under her skin, making her a savage sexual beast (but it wouldn't be kind to do so).
So, as long as the player is normal "free willed", he has last word.
A good player will take your skill roll and your skill level into account. Muro did just that. But in the interest of player integrity neither NPCs nor PCs can "persuade" or "charm" PCs.
PCs must be psionically, biologically or mechanically forced to do stuff against their will.
