*stands and does final checks to her outfit* next time I pick the poison. that gives us no time to get away before it hits him. I think it'd be better if we stuck around, pick up no extra weapons and quickly dispose of the poison container properly, maybe if I can slip it to you after it's placed in his drink, then I can stay by his side as it hits, act distressed, get questioned and throw them off the scent, can also ensure he's definitely dead...
...or we don't get too close at all. Maybe for a while but you walk along and pick me up as he receives his poisoned drink so we're away, maybe say we need to leave or you want me away from him, then we make our get away, sticking around for a short while to check he drinks it and no one else perhaps...
...or we find some way to cover up the whole thing, finding some way or making it seem he's just over drunk and collapsed or...if you come, just after he finishes the drink, to take me away, hit him around a little for hitting on your girl, guards will come and kick you out, I can follow and we can leave quickly as others check if he's okay, by this point he's already dead, while people originally think he's just been knocked cold by your hit...
...or am I over thinking this?...
