Ada's paper plane is an article in Resident Evil Recollections. It was uploaded on 11 May 2015.
Ada seems to be everywhere in Resident Evil 4, saving Leon and making sure everyone knows she still has it. One of my favorite scenes is when she slips past Leon in the castle shortly after their one-to-one "talk".
One thing that always struck me about Ada is her incredible dexterity. You might think of her shooting skills, but what I'm referring to particularly is her paper plane.
In a certain scene she manages to glide the plane through a row of iron bars and have it land right by Leon's feet. I wonder how many tries it took her to get it right? I can just imagine her throwing planes at the bars until it worked...
You can see more Ada than you can handle in the two RE4 subgames Assignment: Ada and Separate Ways, not that I need to tell the Ada fans among you!
