How Far Will Frank Go on How to Get Away With Murder?

We've learned so much about the mysterious Frank Delfino throughout this third season of How to Get Away With Murder, and in tonight's ultra-dramatic episode—the one right before we find out who was on the gurney and just WTF is happening in Annalise's house—Charlie Weber promises we'll learn even more about his character.

"I think you're going to see a very desperate man," he tells E! News. "You're going to learn how far he'll go

, which is a bold statement!"

It's been a fun exercise for Webber to learn more about his hit man character, he says. "It's been great for me to sort of pull back those layers and show people what's inside of him."

But tonight, we'll see Frank at his breaking point.

"He's so desperate right now it's hard to see what else is going on," Weber says. "I hope a sort of sense of need to be with Annalise and Bonnie is coming through because that's sort of his only mission right now."

Spoiler alert: Frank does succeed—he and Annalise do have an emotional confrontation—but you'll have to wait until tonight to see how it plays out. In "No More Blood," Annalise and Bonnie will turn to an unlikely source for help and bring the tension among the Keating 5 to a head.

There's just one more week until the timelines finally catch up with one another as we discover the identity of the victim (in the appropriately titled episode "Who's Dead"), which will also see Annalise receive a tip about A.D.A. Atwood that leads to a heated confrontation with Nate.

How to Get Away With Murder airs Thursdays at 10 p.m. on ABC.
