Actually, and I know this is coming a little late but I've only now read through the thread, Archer letting something slip is perfectly valid.
IIRC, the souls drawn from the Throne of Heroes forget the previous times they were summoned. This especially applies to Counter Guardians, who are supposed to keep the world from going too out of whack, and of which group Archer is a part of. Their work is neither particularly heroic, nor pretty, nor even _moral_ some of the time, but apparently quite neccessary. Or something like that.
Normally, Archer wouldn't have been affected by all those times he had to commit what was basically _slaughter_, since he wouldn't really remember them ...
Unfortunately for him, UBW kinda screws that up, since _whenever he traces his Kanshou and Bakuya UBW has him 'read' the history of the blades and lets him regain all those memories_. His line about 'not remembering' may be true at the start, but it doesn't _stay_ true for very long at all.
Hence Archer being just a taaaaaaad unbalanced, enough to want to kill Shirou to stop him from becoming himself in the future.
