Who is responsible for the bombing of Capitol? Watch Designated Survivor episode 3 to find out

Designated Survivor is one of ABC's steady newcomers and has earned itself a growing political drama fan base since its premiere in September. In episode 2, which aired last week, we saw Tom Kirkman start his first day in the White House as president of the United States.

Dropped into a position he is not prepared for, Kirkman (played by Kiefer Sutherland) has to get accustomed to the crazy pace of the most demanding job in the country while attempting to prove to the many sceptics around that he is capable of the role.

It has only been a few hours since the bombing of Capitol and chaos is erupting across the nation. In Michigan, the police have orders to take strong and violent action against all Muslims with arrests being made across the state. The governor blatantly disregards the president's orders to cease harassing of people of the community, and it is only after Kirkman pulls off a major bluff does the local leader agree to call off the police.

Back in Washington, Seth Wright (Kal Penn), the president's speechwriter is also harassed by the police for being dark-skinned and travelling with a "suspicious" backpack.

Meanwhile, FBI Agent Hannah Wells (Maggie Q) is working on finding out who was responsible for the extensive attack on the Capitol, while trying to control her own emotions as a possible romantic interest of hers has gone missing in the explosion. The FBI Deputy Director is convinced Africa-based terror group Al-Sakar is behind the attack but Hannah has her doubts. Will she be able to prove her theories in the upcoming episode?

On the home front, Alex Kirkman (Natascha McElhone) has to deal with the revelation that her son Leo is dealing drugs — the last thing a nation's leader needs to have the press find out about.

One of last week's interesting twists was the news that Kirkman was not the only designated survivor but that Congresswoman Kimble Hookstraten (Virginia Madsen) was also selected by the Republican side.

In episode 3, titled The Confession, we seen Kimble being supportive of Kirkman but somehow it seems a ruse to get to know her competitor better. She is sure to switch from ally to foe in the future, but for now, it is all political games at the White House.

During a sit-down interview, the president will also be questioned about his job termination, which took place hours before the bombing. Will he step up and reveal the truth or will he take the advice of those around him and deny it?

Last week, the episode ended with the discovery that there was one living survivor in the blast. It doesn't look to be Agent Hannah's boyfriend but could the person make Kirkman's tenure as Potus a short-lived one?

"He's the sole surviving witness to the murder of a thousand people. Don't you think we need to see if he saw anything?" Hannah asks her superior in one scene in the promo.
