Okay lets clear something up about Lanterns
to everyone who is questioning why they aren't making it so John and Hal both get their own rings at the same time:
In the comics John was not a full time Lantern when he was introduced. He was a backup Lantern candidate in case Hal ever got hurt or killed. He didnt get his own independent ring until over a decade later, in Green Lantern #182. Thats what this show seems to be taking from.
They're most likely going to give John his own ring (just like Guy) before or by the end of the show. He's definitely having his own ring by the time of his appearance in Man of Tomorrow
