Romance is in the air in Portland — flowers, passionate kisses and … gunfire. Throw in the green-eyed monster — or a green-eyed human in a jealous rage, to be precise — and you have a little romance, “Grimm” style.

The folks at “Grimm” were busy little bees during their way-too-long hiatus, and packed plenty of action into “Grimm’s” return Friday night. Here’s the basic lowdown: Rosalee (Bree Turner) is back, we finally got confirmation that Captain Renard (Sasha Roiz) is a Wesen and saw his other face, and Adalind (Claire Coffee) is still officially the most evil bitch on the planet.

That’s the Cliff’s Notes version, but let’s fill in some details.

Adalind is still hot to get her hands on the key, and using Renard to do her evil deeds. Speaking of hot, Renard and Juliette’s (Bitsie Tulloch) spell-induced infatuation came to a bit of a head Friday night. While at a crime scene, Juliette called Renard begging him to come over. As if that wasn’t bad enough, Nick (David Giuntoli) knows about the little thing between the two, minus the whole spell part driving it. So he follows Renard back to the house formerly known as his and Juliette’s abode, and is set to storm in and catch them in the act when Monroe (Silas Weir Mitchell) calls him and divulges that whole spell thing.

(Whew, that’s a lot of action for a little bit of screen time. )

Then Nick… walks away. Huh? Whoa there writers, even if this fatal attraction was caused by love potion #666, Nick is really going to leave without breaking up the party? Or at least what he thinks is a party. Nothing could be further from the truth.

Just as Juliette and Renard are about to uh, consummate their attraction, conflicting emotions run wild in a “Yes! No! Stop! Don’t stop!” back and forth that finally ends when Juliette grabs Renard’s gun and fires off about five or so shots to stop the action. Fortunately for her — and Renard — she shot them into their walls, not loverboy.

So he leaves, but Adalind hooks up with Renard, and I do mean hooks up. She wants to take the edge off, so to speak, and insists that Renard get it on with her in Wesen mode. So now we finally see his Wesen face, which seems to be Hexenbiest? Men can be Hexenbiests?

But the most stunning turn of events is when Renard figures out  Nick has hidden the key in his desk at work and swipes it. Then denies having it to Adalind. Then, get this, takes it back to Nick for safekeeping when he realizes handing it over would be his death warrant, at which point Renard and Nick pretty much know all about each other.

Then with the help of Rosalee, Nick, Renard, Juliette and Monroe set about reversing that whole obsession spell. Nick has to drink a nasty potion for purification as the first step to setting this right, just as Renard had done to wake up Juliette, Sleeping Beauty style.

So we find Nick in the throes of a very bad reaction to his purification potion at the end of this episode, and the Wicked Witch of the Wesen, Adalind, has an entirely different reaction to the dose of “love potion” Renard gave her — the skank is knocked up, which clearly pleases her.

What is she up to now?
