Bailey is attaching little nodes to Izzie's head while Derek looks at a monitor, and Izzie just now needs to try and have a hallucination. She then asks Iz if the hallucination is always Denny, which we know it is. Bailey tells her this makes sense, since he is the man she loves, but Izzie interrupts her musing to say that while she will always love Denny and he means a lot, she thinks that he's here because she associates him with death and dying. The man who she loves now, who gives her a flutter in her chest, is Alex. Bailey smiles at this as if she didn't already know this piece of information -- you know, because they've been so secretive about their relationship -- and Izzie sits back to get the show on the road. She says it's time to find the tumor and get it out, "So that we can have our perfect wedding, a wedding not wasted on two people who don't appreciate weddings." What? What's that? I can't hear you on account of the ringing in my ears from the beating I just took with the Foreshadowing Stick. Derek points out that he can hear her, and Izzie knows, because she wanted him to hear it. He tells her that he'll stay until they find it, which freaks her out anew because she refuses to let him be late to the wedding. She then begins to beg Denny quietly to show up.
