In *Lanterns*, John Stewart’s ring sustains a projection of Hal Jordan that appears to perceive events beyond the data stored in it, and can manifest without John deliberately summoning it. The episode suggests John can maintain complex constructs independently of the ring, challenging the usual rule that Green Lantern constructs vanish when their wearer loses concentration or removes the ring.

Earlier, John created a living bird that remained active after he returned the ring and even while he was unconscious. In episode 7, the Hal-ogram asks about a conversation John had outside its storage unit, then appears in his car and refuses to disappear until John concentrates on something else. The article reads these events as evidence that this version of John may be an unusually powerful Green Lantern. TLDR:
– John’s constructs seem to persist without the ring.
– The Hal-ogram appears aware of events outside its stored memories.
– The episode hints John could be an exceptionally powerful Lantern.
