Much of the emotion came from a surprisingly touching storyline between Roy and Karen. Karen's long been a Wisteria Lane favourite, but Roy hasn't always clicked, so it was lovely to see a different side to him in this instalment.
Gaby's got all the childcare she needs out of Roy now as Carlos is coming home soon, so she's keen to reconcile him with Karen. But both Roy and Karen are being stubborn - particularly Karen, who doesn't want Roy to feel obligated to look after her now that her cancer is back.
When Gaby finds out that Karen is sick, she carefully probes Roy about what it was like to look after his first wife, who died from brain cancer. Seeing Roy's tears and hearing him talk gently about how it made him value his wife more - and seeing Gaby's similarly tearful response - could have been cheesy but instead treads the line perfectly.
There's more to come, too, as Gaby tells Roy about Karen and he immediately visits the hospital to take care of her. And what makes this storyline even better is that it has an effect on Gaby, too, who realises that she needs to stop taking Carlos for granted. For some reason, you feel like this time her resolutions could stick.
There were also lots of hidden feelings and hurt emotions with Susan and Lynette, who find themselves locked in a battle over who will take care of Porter and Julie's baby - it's the grandmothers locking horns (with poor Porter - trying to do his best - stuck in the middle).
There are, of course, the standard Desperate Housewives argument scenes (see Lynette reclaiming her bassinet from Susan), but underpinning that are so many more genuine feelings - Lynette's inability to give up control and spend time by herself, Susan's desperation over her fight with Julie, and so on.
In a nice touch, Tom and Mike are the ones who speak to the warring friends and persuade them to patch things up. This plot could have been a superficial joke about fighting grandmothers, but instead there were some relatable, rational motivations behind it all, making it much more interesting.
And that's without even mentioning the genuinely creepy moments of the episode. That glaring loan shark is back, threatening Renee, trashing her home and getting involved in fist fights with Mike. Even though Renee paid Ben's debts, it seems that we won't be saying goodbye to this villain just yet.
More shuddery was the Orson-Bree relationship. Orson's totally won over Bree, but when they leave to go to Maine, things begin to unravel. Bree wants to stop at Orson's apartment to pick up a hideous hat she once bought him, sparking Orson's first flash of anger.
He manages to get into the apartment first to tear all the incriminating photos and clippings charting Alejandro's murder from his wall, but it's not quite enough - Bree finds a photograph of the Housewives and Carlos removing Alejandro's body and puts two and two together.
Orson admits that he was behind the horrendous letters, and makes things even creepier by claiming that he isolated Bree from her friends so he could have her all to himself - he did it all for her! No, Orson, that doesn't make it any less freaky.
Bree stands up for herself and banishes him from her life, though clearly this has shaken her dreadfully. Things take a turn for a worse when Orson calls her and appears to suggest he's going to kill himself, making Bree feel even worse. But what she doesn't know is that Orson is posting a big brown envelope to the Fairview police...
This episode, then, was full of Desperate Housewives goodness - emotion, humour, and some serious creepiness that leaves us on a big cliffhanger about what could be coming next...
- I enjoyed the moment when Lynette and Tom - telling Porter that they couldn't provide daycare - lost Paige. Tom's "found her!" from another room was fun.
- Also, Porter's suggestion that he would call the baby Lynette. "That is incredibly touching!" Lynette smiles, before her hard-faced "it changes nothing."
- The whole Orson storyline was enjoyably creepy, but I liked the moment when he slipped up and mentioned the "letters" Bree had got, when she'd only told him about one. Tense.
- "It's about time you started calling me Susan." "Or better yet, grandma!" "No. Susan."
- Gaby turning Karen's sentences around - "your finger's bleeding" - was brilliantly childish.
- "Let's hope the baby takes after Julie."
- That loan shark is ridiculously menacing - it's a bit over the top. But hey, this is Desperate Housewives - I'll let it slide.
- "Do you want to have sex with me? That would really p*ss her off."
