What can you tease aboutOnce Upon a Time?

Cant say more than that, but you may find a hint in this weeksHot Seat.

IfChase is Prometheus, then who is under that Vigilante mask onArrow?

MaggieAlas, we wont find out soon.

We know the answer to that, executive producer Marc Guggenheim says.

You probably will not get the answer to that in season 5.

What can you reveal about Alex in next weeksSupergirl?

CharlieWell, shes going to some dark places in the wake oflearning her fatheris colluding with Cadmus.

Basically, Alex goes head-to-head with Lillian Luthor, so its a really powerful episode.

Anything on theVampire Diariesfinale?

Spoiler alert: You hear that line in the finale, executive producer Kevin Williamson says.

Theres little Easter eggs like that throughout the whole thing.

So which lines do you hope to hear again?

LouIm so glad you asked about Henry, the consistently forgotten Jennings child!

Without spoiling too much, this season just might be the best one yet for Henry fans.

Henry is in a very interesting position this year, writer-producer Peter Ackerman says.

Adds creator and executive producer Joe Weisberg: Its kind of abreakoutseason for him.

Better that than breakingintohis neighbors house, as he once did in season 4.

Did all those Daisys die in the HQ explosion onAgents of S.H.I.E.L.D.?

So maybe dont hold your breath?

Any Malec sccop for theShadowhuntersfinale?

I cant say what it is, but expect Malec to make a big decision by the hours end.

How did Red have so much info on Tom onThe Blacklist?

Is he connected to Christopher Hargraves disappearance?

KyleJust because Red knew Tom was Scotties son does not mean he played a role in the abduction.

In fact, the writers are trying to keep the mythos of each show somewhat separate.

What Reddington told Tom was to stay away from it, EP Jon Bokenkamp says.

Red is not somebody who has a tremendous amount of love for Tom.

Theyve had their own fraught relationship, but that did seem genuine.

Of course, hes always full of secrets, so who knows?

But it feels like it stands on its own.

Will the Mahoneys return next season onHow to Get Away with Murder?

BrendaSurvey says: Its likely.

H.G.s time machine gets put to good use.
