Jack doesn't have a satellite dish on him, though Code had one earlier - did anyone pick that up? If not, Jack could ask Hector to route the call through his external link?
Thinking out loud... I wonder if playing back the trid for the elf Holland showing what happened, and then finding a piece of mirror and showing him himself in the mirror and forcing him to see what he'd become... that might just piss him off, but it might get him depressed/distracted enough to drop the spell. Hard to say... and it means sending someone in to talk to him.
Also, what to do about Gardener... he's down on 104 still (I believe).
