Now that the entirety of heaven's host has crashed down to earth, the newly displaced angels will be causing a few problems during season 9 of Supernatural.

When the credits rolled on last spring's "Sacrifice," Metatron (Curtis Armstrong) had seized power in heaven, Castiel (Misha Collins) has lost his grace, and an alarming number of angels had become fireballs as they plummeted to earth.

Now, Supernatural's cast and crew have leaked a few details regarding the angels' powers, the return of Metatron, the resurrection of some deceased angels, and a possible romantic dalliance for Cas.

Unlike the graceless Cas, it appears that the fallen angels will retain most of their powers.

"The angels that fall have full angel powers but they don't have any wings, so the only angel specialty [they are lacking] is they can't teleport," said executive producer Robert Singer during the San Diego Comic-Con, according to Give Me My Remote TV. "Other than that they can do all their angel stuff - they can smite, they can heal, do the things we've come to know from angels."

This could cause a few problems for the people of earth as well as the angels themselves. As some seek to find a way back to heaven and others try to settle in on earth, Singer says that battles between different factions are inevitable.

As for Metatron, viewers won't be seeing him until at least mid-season.

"I can tell you that while he exacted his revenge, he's finding it a little lonely up there," Singer said in an interview. "There are non-angels up there, there are all the souls that have risen to heaven, and he doesn't really have anybody up there to keep the electricity on."

Meanwhile, there may be a few unexpected angels among the numbers on earth.

"I know there are angels that we really like that we killed off... [and] yes, I think we will reintroduce some angels," Singer teased fans.

Could this signal the possible return of Gabriel (Richard Speight Jr.)? If the self-proclaimed Trickster does make a reappearance, he will certainly be intrigued about Cas' upcoming sexual exploits.

"There is sex that does occur between Castiel and a person," Misha Collins coyly informed fans at last weekend's VanCon.

It appears Cas will finally have a chance to display a few of the lessons he learned from the pizza man.

Supernatural returns to the CW on Oct. 8.
