Team has been given clear order - split up and filter building of enemies.

You sneaking around third floor, holding rifle at ready, when you hear quiet footsteps behind you. Without turning around, you recognize them - it's Simon.

He was supposed to be an other floor, instead he followed you. To be honest, it's starting to annoy. You're fine soldier, not kid who's been given gun to hold.

But Simon was stubborn - if he chose to be your protector, he would do it whether you liked it or not.
