If Season 9 of Grey's Anatomy has been a little too heavy for you, you’re in luck. Season 9, Episode 4: "I Saw Her Standing There" (airing October 25) is full of fun, laughs, and has a generally lighter mood than the emotional first three episodes of the season. Oh, and the Kevin McKidd (Owen Hunt)-directed episode features sexcapades all over the place.

Here are five major clues taken from the sneak peeks and promos.

Catherine Avery is back in Seattle, making Jackson (Jesse Williams) feel uncomfortable, and turning Richard (James Pickens Jr.) on.

Calzona is on very fragile groundArizona (Jessica Capshaw) is still holding on to resentments towards Callie (Sara Ramirez) for making the hard decision to amputate her leg, and now she has to face the reality of her condition by training with a prosthesis

Cristina (Sandra Oh) has a “sex friend” in Minnesota, and we are dying to know who he is and how she feels about it. And April (Sarah Drew) and Jackson just can’t keep their hands off each other. Something tells us Bailey is in for a rude awakening when she finds them doing it in the attendings’ lounge. Just a guess!
