well for some this is new and others this happens every time they log in, if they play their character in character, and in local area chat narrate to others with all references to the real world we know as unknown future events decades away. ie no chat about internet, the car, current events or anything not known to that character in the game time frame in which they personally "live". and in the case of "mad" molly any loyal member of the" british empire" or the commonwealth itself would be swore enemies to her ( check her back story to learn why and how to possibly change her opinion)and just as likely , hard for her not to want to kill them, unless the price or a good reason not too of course. RP can be a very closed world set of situations set forth by a story masters idea of what it should be but often each character must remain true to their their own story and act and react accordingly, to what is known to the character not the players knowledge. regardless of the storytellers desire or intentions. to allow for this it is common in rp situations that no one emotes the effects they have on others IE but what they wish to do and the result is emoted back by the other person involved. Nor impose their intentions on others, by emoting they are doing something the other character themselves dont wish to do, but simply rolling open ended with the offered situations and always always leave others a way out of a do or die situation. no one is all powerful or all controlling over another.the goal is to keep the story or situation going to a fun and enjoyable outcome to all not a one up fest.
likewise any active rp character should have a backstory, intro and starting point no matter how vague from which to "live out" the characters actions from, this may or may not be common knowledge to someone they just ran into so also never assume until you converse and learn it while playing your character knows anyone. use of chat like molly looked at the man with fire in her eyes and exclaimed"worthless bilge rat" , under her breath. as "in character chat" the descriptive of what she is doing and the " " denotes actual comments spoken and (welcome to the guild) denotes non in character chat is another tool to help keep it sorted out.
for those new to rp hopefully this will just offer a taste of what is possible, and if you ever happen to catch up with molly in game she will act out as herself( not the person controlling her in game character) in local chat and speak accordingly to those doing likewise , be warned from tavern talk that this gal can be quite "mad" both in her fiery irish temper and day to day actions lol
