In Jak 2 errol crashed into the dark eco barrels, and in Jak 3 was rebuilt as a cyborg. Who rebuilt him? The dark makers or the KG? Why would the Krimson Guard do it, if errol was loyal to the baron and at the end of Jak 2, the Baron was gone and they got rid of the dictatorship? The Freedom league wouldnt rebuild him.
I don't think the dark makers rebuilt him either. That seems kinda random. What would they be doing in the stadium during Jak 2?
