Scenario 1. I play Poisoned Wine on my opponent's character.

"Any phase: kneel 1 influence to move Poisoned Wine to another character"

my opponent then tries to kneel 1 influence to move the attachment elsewhere. I thought that this was not allowed, as I still have control of the attachment, therefore only I can invoke it's powers. She reasons that you can always get someone else to taste your drink.

Scenario 2. Melisandre (RoR) wins an intrigue challenge and takes a power off of Rakharo, who has renown thanks to Aegon's blade. This is the last power on him, so he dies. However, he has a duplicate. Can the duplicate be discarded to save him, or is this a terminal effect? I thought not, as it says "if it is the last" rather than "if the character has none" but it'd be good to have a clarification.

1) yes you move the card, not opponent

2) yes dupe would save him if he again has power and has it taken would die then.

Only the person who controls the attachment can activate the abilities of the attachment. The person who controls the attachment has nothing to do with either the character it is attached to or the name of the card.

She'd need to say something more like "while this character has no power on it, kill it" in order for it to be a terminal effect.
