Alexander Skarsgard Alexander Skarsgard

Fans of Charlaine Harris' Sookie Stackhouse novels, on which HBO's True Blood is based, will be plenty happy very soon. Why? Several key elements from the books will pop up this season and next. Sexy shower scene, anyone?

Here's what learned during Friday's True Blood panel at Comic-Con:

1. Eric and Sookie. Shower. Together. Alan Ball won't say whether or not Eric (Alexander Skarsgard) will remember his current time with Sookie (Anna Paquin) — if he gets his memory back — but we sure hope he remembers their time in the shower. Oh, yes, that is coming. "There will be a moment in the show where Sookie and Eric are together in a shower," Ball says. "It may not be exactly what's in the books. It may be weirder and dirtier. Maybe."

2. When Eric bit Pam... For those wanting to see how and why Eric created his progeny, Pam (Kristen Bauer), Ball promises we'll see it in Season 5.

3. Vampires unite! With witches running rampant in Bon Temps, enemy vampires may be calling a truce for their greater good. Does this mean Eric and Bill will team up? Here's how Ball puts it: "The entire community is pretty much under siege during this season. I think the vampires will stick together to fight the common enemy."

4. Twin fairies? Eric may have vanquished the faerie godmother Claudine (Lara Pulver) a few weeks back, but that doesn't mean it's the last we've seen of Sookie's faerie family. Says Ball: "Those of you who know the books, know that faeries are born in litters — and they're identical." The question is: Who has a twin? (Book fans know!)

5. The rise of Hooligans. Asked about Hooligans, the strip club where a very special faerie works in the Sookie Stackhouse novels, Ball says the show will erect something similar. "It may not have the same name, but there will be a business venture that involves people of both sexes taking their clothes off for paying audiences," he said. "It will have a completely other twisted supernatural purpose in Season 5."

6. Vampires, werewolves, werepanthers, witches... and ghosts? It could happen! "We will see spirits without bodies. We have seen glimpses of a particular kind of brujo-based, freakish creature-slash-demon-slash-something you're going to see a lot more of this year," Ball says. Use your imagination, kids!

7. We like the Sookie Stackhouse books too, but... Future seasons will stray further and further from Harris' source material. But, Ball says, the show will always "try to remain true to the spirit of the books."
