Ianto was pretty sure that Jessica wouldn't have liked it any better if she knew what Jack had wanted to do in his dreams. And considering the fact that she was a teenage girl, with teenage emotions, multiplied by ten because of her supernatural powers, Ianto didn't believe for a second that she'd be able to put up with the awkward for a minute, when she found out that all Jack wanted was to find a way to die.
"I don't hate you," Ianto said, "I don't know you. But let's be honest--whether you're proposing that I whisper sweet nothings in your ear while you suck on Jack's neck, or just contact you in case I hear of any supernatural emergency--there's no way we're not going to be jealous of each other. And Jack will burn himself out trying to please us bother. You know he will. Tell me what part of that sounds like a good plan?"
