After Deathstroke sneaks into the Arrow lair, Oliver looks ready to spring into action in "The Man Under the Hood."

Felicity does a good job of ducking and covering as the rest of Team Arrow takes turns trying to stop Deathstroke.

Something tells me a bullet isn't going to do much to Deathstroke. First the cool outfit then the Mirakuru? Yeah, don't think so!

Diggle takes a turn on Deathstroke. All the kings horses and all the king's men (remember, Roy called Ollie King Queen...)

Slade's outfit hides too much hottness, if you ask me. Oh you didn't ask? Carry on.

Are the sparkles a result of something hitting Deathstroke's suit? Preeetty!

That's gotta hurt. All of that glass in the Arrow lair is going to get someone injured someday!

Sara is on the attack, flying in from high in "The Man Under the Hood."

Tiny Sara isn't much of a match for Deathstroke, either. Team Arrow could be in trouble!

Will Oliver be the member of Team Arrow heading to the hospital? We'll find out how good he can fight in "The Man Under the Hood."

How can Oliver fight Deathstroke? He's highly unmatched without the Mirakuru running through his system.

Team Arrow comes together for a meeting. Are they trying to decide how to keep Slade from infiltrating the lair again?

It looks like Sara and Felicity are great support for each other. Who imagined that would happen? From the looks of it, Sara was in the hospital. Wrist brace!

Oliver is surrounded by what will become Slade's Mirakuru army. Or will they? What will Oliver do about them? Find out in "The Man Under the Hood."

Oliver Queen is the man under the hood. It's a secret that Laurel Lance now knows.
