What should the post credits scene be?

Post credits scenes that I would use:

- Hal Jordan and John Stewart are back on Earth and find their way to Wayne Manor. The 2 of them are at the door and ring the doorbell. Alfred answers the door and asks them how he can help them. Hal and John then ask if this is Wayne Manor as they are looking for Bruce Wayne and that this is the address they got. They show their Lantern rings to Alfred as they flash with Lantern power. Teases them in the DCEU Justice League. (#1)

- Meanwhile on Oa, Sinestro has escaped and makes his way to Earth. While on Earth, he runs into Lex Luthor. (#2)
