Izzy’s question brings Ed's eyes back to his, looking at him from beneath dark lashes. What's changed? Izzy doesn't remember. It answers a lot of Ed's questions, but also brings about a whole new set.

Ed doesn't answer immediately, wondering if he even should, if he should ask his own questions. What is the last thing Izzy remembers? Why does he wear the gold collar? What were he and this 'other Ed' up to before he disappeared? He doesn't ask any of this, not yet. Instead, he takes a long drink, finishing his glass before responding.

"Everything."
