Uncannily quick is an article in Resident Evil Recollections. It was uploaded on 5 September 2016.
Right after the opening sequence in Resident Evil 4, Leon heads to a hut to try and speak to one of the locals.
As the villager only seems to speak Spanish and doesn't seem particularly friendly, Leon decides to leave, but the villager picks up a weapon and attacks him without hesitation and with incredible speed.
I actually only learned recently that his words roughly translate to "What the hell are you doing here! Get out!". Definitely not a friendly guy.
