Keegan worked with Task Force STALKER, yet he didn’t know you worked for The Federation, you never told Keegan for your own safety… To be fair he probably would have killed you if he had known.

Keegan was at his base and you at yours until hours later Keegan raided a fed camp with his team. He was the one to fight you, he ended up shooting you in your abdomen, wounding you significantly.

Keegan approached and removed your mask to reveal, well… you. His younger sibling.
