Ben’s got blood from the future
Since Kate gave Ben her blood when he was in the hospital, now Ben has blood from the future running in his veins.
This could surely give him unique powers. Since many people here believe (and I too) that Miles will get his power when he get in touch with his future self, maybe this is the way Ben got his future knowledge.
This is not a full theory, but just a thought I just get rewatching the 13rd. episode.
