Universe C (Shippy Shifter Snippets)
From Jenny Everywhere Wiki
In one universe, Jenny Everywhere was a case worker. This universe was connected to a version of the Infinity Train, which was sufficiently otherworldly to have its own Jenny, but although the Train Jenny did not have the ability to shift outside of the Train, she had access to the telepathic network and thus the two were aware of each other. This allowed Grace Monroe, who had begun to form a relationship with Jenny aboard the Train, to carry it on with her human counterpart after she had to return to her own world.
