Scott (Tyler Posey) and his pack will be facing their toughest foe yet in the upcoming episode of MTV's hit series "Teen Wolf."

In "Status Asthmaticus," the International Business Times reports that the wolves will find their powers and brotherhood tested as they battle with the strongest opponent they have ever encountered. This fight will be infinitely more difficult for them. Aside from worrying what is at stake if they lose — more lives will be lost — the pack is also facing some trust issues among its members.

Last episode, Scott finally found out Stiles' (Dylan O'Brien) secret. The Alpha has connected Donovan's (Ashton Moio) death to his best pal, and was aghast about what happened. When Stiles begged for forgiveness, he was told by Scott that they do not kill the very people they have sworn to protect. Stile was devastated that he disappointed his Alpha and his dearest friend, but he could not believe what Scott did next. He kicked Stiles out of the pack.

Now, they will be facing the enemy minus Stiles. No matter how tough Scott pretend himself to be, what happened will inevitably weigh on his mind. The pack is not ready for this challenge. Will they be able to defend the town from this menace? And what about Scott, who could also be fighting incapacitated?

According to the website, the title of the episode pertains to successive asthmatic attacks. The Alpha is known for this affliction, as only a few episodes ago, his attacks gave the pack quite a scare. If he faces the enemy in less than perfect condition, it could mean an easy defeat for his team.

And where will Stiles be during the confrontation? Will he be helping his brothers, although the Alpha has already denounced him? Will he and Scott be able to work things out before the season ends?

"Teen Wolf" airs on Monday at 10 p.m. EST on MTV.
