If you don't know the history of S.H.I.E.L.D. by now, there's no excuse... unless you fell asleep in Professor Vaughn's class... that's a perfectly acceptable excuse.
Te peaksite juba tundma KILP-i ajalugu, kui te just professor Vaughni tunnis magama ei jäänud, See oleks täiesti aktsepteeritav põhjus.
