Okay, ya made me go back and check ...
Yes, Vol 2 does have the origin.
Now, one thing, don't pay full price for the Goon. There is a lot of cool art, and the story can be funny, but there are a lot of times little happens. Make sure if you go goon, go cheap.
Didn't you know? Cheap is my middle name! Less than $7 brand new cheap enough?
Amazon has it for less than $12, and I got a leftover $5 Amazon GC lying here somewhere....
The Goon Volume 2: My Murderous Childhood & Other Grievous Years (New Printing) (Goon (Numbered)) by Eric Powell (Paperback - Oct 20, 2010)
