Steins;Gate (Dub) 16

Unable to get much information about the badge maker’s client, Okabe decides to leap back in time to confront the client in question, only to find it was Daru, who wanted to make a fake badge to cheer Suzuha up. Daru then reveals that Suzuha’s time machine is only able to travel backwards in time, meaning they won’t be able to see her again once she leaves.
