The Stalker
In the old days, he would need to maintain visual of his subject. And there are tricks in order to avoid detection: hug the horizon. Hide in plain sight. Determine her blind spot, and hide there.
But now, with the GPS tracker, Gabriel can maintain a safe distance. The little blue circle that blinks on his phone's screen is Claire, and he doesn't have to panic even when he doesn't actually see her. And besides, the four bodyguards are spread out in all directions.
But then again, this is Claire dating his brother—why so heavy-handed? This isn't another Jake Magno. You can actually relax, because although Miguel's such a womanizer, he doesn't try to drug and date-rape people.
But still. Gabriel is overcome by a powerful sense of protectiveness. He couldn't bear the thought of not seeing Claire, knowing she's with another.
Or maybe…he's just jealous?
