#1 What specifically did he do/or lie about, that squashed his deal with the government?
Also: Was it ever stated what would have been the best case scenario, had he co-operated fully?

#2 How long was he actually on the run for?

#3 Why in the heck would he hide out at a home that has ANY connection to him at all? I don't doubt D'Arco knew about his mistress.

#4 Why didn't Vic shelve him the moment he decided to co-operate? He may very well be shelved now but, I have not seen source list him as being shelved.
