The hiatus is almost over and the Girl of Steel (Melissa Benoist) will be back for another high-flying adventure when Supergirl returns next week.

To whet our appetite for the superhero series' latest installment, The CW has released a new extended trailer for “Ace Reporter,” along with a bunch of pics from the episode guest-starring iZombie’s Rahul Kohli as Lena Luthor’s (Katie McGrath) former boyfriend Jack Spheer, aka Biomax.

The trailer is filled with exciting new footage and features Mon-El’s (Chris Wood) mom Queen Rhea (Teri Hatcher) of Daxam and President Olivia Marsdin (Lynda Carter), who’s actually a shape-shifting alien called a Durlan (this was confirmed by Carter herself).

Read up on the synopsis before digging into the new trailer and the gallery of pics below (via FarFarAwaySite). Oh, and someone else knows Kara is really Supergirl. But who?

Lena’s (guest star Katie McGarth) ex-boyfriend, Jack Spheer (guest star Rahul Kohli), comes to National City to unveil his big breakthrough in nano-technology, which has the potential to eradicate all diseases. Lena asks Kara to attend Jack’s conference with her for support. When Kara sees Snapper (guest Star Ian Gomez) in attendance she’s inspired to tap back into her reporter skills and questions Jack on his discovery, which ultimately leads to a bigger investigation that puts everyone in danger.

Supergirl returns on Monday, April 24, at 8 p.m. on The CW.
