While in control of Skittle's body, there was no need for him to look at where his actual body was because he had given his body a single command with the help of the system. And the command was to protect Skittle from any danger.
Doing this meant that his body would take the quickest route to reach Skittle. Zain didn't know what would happen on the way or whether his real body would run into danger. However, when his real body was close, a system prompt flashed in front of him.
The system prompt alerted him that his real body was close. Still, he was in danger and didn't know when his real body would get here, and he could rely on that information when he had someone right on his back. However, just then, he saw his real body.
