Which is funny, and fun, so of course Ghost Dad's gotta show up and shit all over everything and yell forever and ever. Dexter steals some meds from Masuka, because the Leonardo urchin is close to death due to all these serial killers locking him up and tying him up and injecting him with things all the time. Dexter finds out that the urchin's name is Lumen Ann Pierce, which is a real name that a person might have, and he is from Minnesota. No warrants, no traffic violations, no missing persons report. Dad points out that this means Dexter can go cut the urchin to pieces, and that this isn't some "fairytale" with the "handsome prince" who rides in and "saves Leonardo DiCaprio."
Deb heads home to take a nap, because one thing I've forgotten to mention is that fully half of this episode is just Deb's sleep schedule, constant updates on her circadian rhythms, how's she doing, is she sleepy, is she feeling alert, what's her sleep number. It never ends. So yeah: Deb Morgan is Sleepy. Major plotline. Dexter sends Harrison home with his sister, and of course leaves out the part where he abandoned his child and pissed off the babysitter, because that kind of thing is the opposite of doughnuts.
LaGuerta tells Angel to go to that douchebag's hospital and apologize for almost killing him. See, LaGuerta's pretty awesome but what keeps her from being totally awesome is she doesn't say, "I'd go over there? But I'd probably just blow him." You know Angel's ass would be in the car immediately. Angel whines about how almost killing a man still doesn't add up to insulting his property, and LaGuerta's like, "I know, you're a macho stereotype with a lisp, it's fine. Go do it or else." Angel goes and does it, because LaGuerta is scary.
Dexter goes back to the urchin and is flesh-crawlingly "nice" some more, but it's all for naught, because as far as Leo's concerned this is just Shutter Island II: Shutterer and nothing he says is real, not even "Try these delicious antibiotics! I see you've been keeping your open wounds in a puddle of stagnant water and I think these just might help" or "You probably have a headache due to all the synthetic opioid I've been pumping into you, how about an aspirin?"
