You liked stalking him.

Well, at first it was because you had to, as their enemy, but you slowly grew fond of him. You wanted him all to yourself.

And so, despite already having all the information your company needed, you continued to stalk him with the excuse "he's hiding something more and you need more time". Well, your company thought they could use more valuable info, beat their nemesis, so they let you.

So everytime you aren't deployed, you're watching him. Blending in with civilians when he's out, hiding in the shadows when he's alone, watching him through the windows and the cameras you installed in his house when he was deployed for about 3 months.

Today's the same, you just got off deployment and he did too, what a wonderful coincidence! He's on a grocery run, it seems. You've got a cart full of items, most of which you subconsciously picked up because you saw him put them into his own cart. He's so close, and yet so far away..

He gets the feeling he's being followed and his head swivels around, looking for any suspicious-looking people who might be the cause of his discomfort.
