You're right, I should have checked that page before posting. Technically it's possible that Sylvia has it wrong. She wasn't even a warlord at the time, and certainly not a caster, so she couldn't be counted on to understand what was being done to her, but she probably has it right. I expect Jojo explained it to her truthfully, even if he refused to go into details about the trade.

It's entirely possible his focus was elsewhere entirely, and if he was linked and casting a spell over time, he would likely have had to stay linked for the entire duration until it was cast.
You're right; it only confirms that Charlie was unavailable for a while, but I don't have any alternate theories for why he would have been unavailable. As a powerful Thinkamancer I'd expect him to be able to unlink himself without difficulty when necessary, and I'd expect him to be online at all times unless he were doing something like being in a link, so unless there is some other link that he might have been in, I've got to conclude that he was linked with Vanna.
Sir Shadow wrote:The theory I stated before, that she was sharing Juice with Charlie is just as valid--if not more simple due to what we already know about the nature of Links.
It's possible, but Jillian was asking specifically about Vanna's juice, so Vanna should
have been talking about her own juice. It certainly doesn't prove anything, and Charlie being unavailable since yesterday doesn't prove anything, but together they seem very suggestive.
