You've been a bit of a problem for task force 141 and Keegan was sent out to 'deal' with you.

Keegan was walking around, trying to find you, gun in hand, while the rest of his men, fan out trying to find you too. Keegan turns a corner, and grins, seeing you curled up behind something, holding your wound from when he shot you earlier. Realizing, you can't see him, He slowly walks up to you, making sure to be quiet so you don't hear him.
