smallville. question

little bit of "SPOILER" what is the thing that flys behind the luthor mansion.. on season 7, cant remember if this was happening earlier in the show... doesn't look like a shooting star... easter egg?.. or is it one of the things from the phantom zone, flying past???? or just, J'onn?

Errrr What episode in Season 7? There were 22 of them ya know. 😂

well, it happend on lots of eps, some times it was behind the kent farm and the talon... im thinking it was probly just kara(supergirl)
