I am – Hercules!!

For those who missed the news since last week, SciFi has ordered 13 fourth-season episodes of "Battlestar Galactica." They will shoot this summer and likely air in January.

What we think we know about tonight and in the coming weeks, invisotexted:

* It’s the 29th anniversary of Bill Adama’s wedding, and we get to meet Lee’s pretty blonde mom via flashback (or something akin to flashbacks).

* A phone call from Saul Tigh appears to have triggered the end of Adama’s marriage.

* Mr. and Mrs. Galen Tyrol get trapped on the wrong side of an airlock without spacesuits.

* In a matter of minutes all their air will have leaked into space.

* The plan is to pull a Dave Bowman. Blow the hatch and expose the couple to space until a waiting raptor can grab them.

NEXT WEEK: “Dirty Hands,” co-written by Jane Espenson, looks at matters of class struggle as the fleet contends with labor issues.

THE WEEK AFTER: “Maelstrom,” the big Starbuck-centric episode that reportedly shakes everything up but good!

10 p.m. Sunday. SciFi.
