Once Upon a Time season 5, episode 3 is all about new bromances, rekindling old flames, and making sure that evil doers are kept in line.

It’s not easy loving someone who has a tendency to retreat into the darkness. As fans learned on last week’s Once Upon a Time, Belle understands the challenges of loving someone whose desire for power outweighs their ability to love. Hook finds himself in a similar situation after Emma embraced the magic of the Dark One leaving only a shell of the woman he loved behind. But just as Regina is not giving up her campaign to convince Storybrooke that she can rise above her evil past, Hook does his best to find a way back to the Emma he used to know and guide her back to the light.

There are still many, many details from the heroes’ time in Camelot required to paint a complete understanding of where we are in the present. Tonight’s Once Upon a Time season 5, episode 3, “Siege Perilous,” will see Arthur and David on quest to recover an object that may be the key to achieving communication with Merlin, who is trapped in a tree. While they are off, Regina must stay in character as the Savior to ensure that Emma’s true identity remains a secret.

On top of the pressure to release Merlin, Regina has a few personal matters to attend to as well, including an unruly sister who is fresh out of second chances.

‘You forgot who I am. The Evil Queen.’
