Just when you think Oliver (Stephen Amell) and Felicity (Emily Bett Rickards) have cleared their last hurdle, Arrow throw another one in their way. It's the end of an era, guys. Olicity has officially called it quits — professionally speaking that is.

Okay, that was harsh, but let's break it down.

Oliver survived a rollercoaster of emotions this episode, but that was mostly because Diaz (Kirk Acevedo) had him drugged with Vertigo. That drug is seriously the little green pill from hell, and we'll never be rid of it! After losing the entire New Team Arrow and Diggle (David Ramsey), Oliver was already barely keeping a handle on his feelings, and the drugs did a number on him.

First, he lashed out at the police captain and D.A. investigating him for charges of obstruction. Then he hallucinated Adrian Chase (Josh Segarra) harassing him and Felicity leaving him. He even took out his feelings on poor William (Jack Moore), scaring the boy half to death.

Like most people who hit rock bottom though, the clarity of sobering up provided him with a life-changing revelation: He needed to get back to basics where vigilantism was concerned. If you're thinking, "Yay, more Original Team Arrow," you're not going back far enough. The Original Team Arrow was Oliver. Full stop.

In an effort to do the most good with the least collateral damage, Oliver decided he needed to put on his old hood, and go it alone. Without any partners, backup or even Overwatch to help him out. That's right, Felicity is officially off the team.

This is a terrible idea. But whatever, Oliver. You do you. You'll certainly have plenty of free time to do so.

In addition to getting drugged, having it out with his colleagues, his wife and his son, and generally having the worst day ever, Oliver found out he was officially getting impeached. Bye-bye cushy mayor's office!

At the end of the day, everyone knows that this "break up" for Oliver and Felicity as a crime-fighting duo isn't anything to get stressed over. In fact, this episode weirdly highlighted the strength of their relationship and how deep their fear of losing each other ran. Whether or not they decide to return to their working partnership eventually will have little to no bearing on their relationship as husband and wife, and that's when you know you've got a solid foundation. Olicity for the win.

On the other hand, if Oliver absolutely has to choose one thing to let go of, it should probably be his position as mayor. It hasn't done much for the overall plot — besides give us serious Trump vibes — and it's frankly one of the less exciting parts of Oliver's storyline lately. Power is awesome, but if he can't make time to save the city and run it at the same time, then he should probably hand the reins over to someone else.

Arrow airs Thursdays at 9/8c on The CW.
