User blog comment:Zeldakasumi/Is Mr. Braun a Rounder in the Steins Gate world line?/@comment-26377724-20150513105945

I have a good explanation of the SERN connection, it's not MrBraun the key, it's Suzuha, in the "R" worldline, the one Okabe disappear, Kurisu build a time machine and told about her story to Suzuha, and to save Okabe, Suzuha need Kurisu to become an observer of the world, in other words she need kurisu to make a time leap machine. She is also the one who lead Kurisu to use SERN, a microwave and a phone. Why doesn't she prepare the building of the time leap by making a jump at an undetermined time to set the connection herself?
