A lot of things happen in this episode: We fight the Alter-Ego yet again. For some reason, I don't think he'll be coming back after this. (Destroying the Slothoid event first causes him to disappear from the Piscine timeline, but screws them up in the process.) We meet our Future Selves, send the code, and finally get something out of it. Useful Information: If the number is correct, the comlink can be reestablished. This also works for all other interactions with your Future Self. The Reptoids are still jerks.
