Phlox eats. T'Pol doesn't. Phlox confirms that T'Pol wasn't banging around Engineering earlier, and T'Pol asks what he was doing in there, since she's the one monitoring the engines. If that's the case, then why did Trip give Phlox a tutorial? Phlox finally confesses that he could've sworn someone was in Engineering with him that day. He realizes it can't be a member of the crew, since everyone is in "deep neural sedation." And this is where I think Phlox's subconscious decides that if it's not his Imaginary Vulcan, and it's not a crewmember, it has to be something else. Hence the apparitions later. Phlox talks about how crowded and vibrant Denobula is and how much he misses the sociability. He admits to being stressed out by being the only two people awake on the ship. T'Pol apologizes for letting him get lonely, and finds it ironic that she should be his sole companion, since Vulcans spend as much time seeking solitude as Denobulans do seeking social interaction. "At times it has been trying for me to exist with eighty humans -- especially the more irrational ones," T'Pol says ruefully. "Such as Commander Tucker," Phlox smiles. Without admitting to any sort of hanky-panky, T'Pol says she's found the last few days to be a "welcome respite." Phlox feels her, but says he won't complain about movie night being overcrowded ever again.
Sickbay. Phlox continues his letter to Dr. Lucas, in which he again reiterates how much he misses his homeworld. He walks into Quantum's Quarters and says, "Good afternoon, Captain. How are we feeling today?" He checks that everything with Quantum's brain is tickity-boo, and is distracted by more metallic noise. To me, it just sounds like the way a water-faring ship sounds as it expands and contracts in the water. Phlox goes over to the window and looks out. There's a screech as a weird shadow passes over Phlox's face. He leaps back. Okay, that? Freaked me out! I didn't see it the first time around; now I'm recapping in broad daylight, and I was expecting something of the sort in this scene, but it still made me jump. I think it's because I have this insane fear of looking out of a window into darkness and having something pop up right in front of my face. Heart Attack City. Phlox is of the same mind as he comms T'Pol.
