After this cutscene, The Way Onwards will show up on the map.
After beating Level T-7, a cutscene featuring the Runner and the Skater will begin. The Skater meets up with the Runner at the end of Level T-7, where the Wormhole can be seen very clearly. He complains to the Runner that they were "almost there."
At first, he doesn't even know what the Wormhole is, only that they're trying to reach it. The Runner explains that the Student had identified it as a wormhole earlier, and that it connects to another point in the Universe. The Skater asks how they're going to reach it from Level T-7, but the Runner seems like she didn't plan to start from there. She tells him, "First, let's try the easy way: Check for any tunnels we missed." Then the Skater skates back the way he came to start searching.
