There's a DC Easter Egg at the end of Ep 9 but it's a blink and you'll miss it.
Also what happens at the end not the very end of Ep they took the idea of what happened from The Death and Return of Superman.
Ep 11 "Strange Visitor From Another Planet"
Kara must help Hank face his painful past when a White Martian, a member of the alien race that wiped out his people, kidnaps Senator Miranda Crane (Tawny Cypress), an anti-alien politician. Also, Cat’s estranged son, Adam (Blake Jenner), arrives in National City. (Blake Jenner is Melissa Benoist real life husband).

Now that IS a nice picture.
I hope it returns to Sky1 soon, I'm onto ep 8 now, the hiatus has helped & I'm ready for the rest of the season
At the moment GeekTown have it down for a March return.
