The word 'transplant' is most widely associated with organs; most commonly the removal of one person's to put in another. It can also mean the transplantation of the same person's living tissue to another part of the body. OR, it can have an entirely different meaning. To transplant can also mean to move or be moved from one place to another.
As I have mentioned previously, [H]ouse titles often have layers of meaning or apply to more than one aspect of the episode (often main plot and sub plot). I will take a gamble and say that in this case it will mean House being transplanted from jail to hospital (hopefully to PPTH to add a controversially dramatic level) to get the treatment I theorised that Annable's character would give him (some sort of surgery: mentioned in "A Close Encounter- The 'Change' Aspect). On a more medical (and more obvious, though perhaps misleading) level it could mean that House himself will be getting a transplant.
I have NO medical knowledge other than what I've learnt through TV shows, documentaries and common sense so forgive me if what I say next is complete nonsense.
Scenario ONE: Say a prisoner dies, someone House tried to save for a while, someone who he became close to (a jail Wilson). This prisoner says that when he dies House can have his organs/living tissue; in this case his thigh muscle. Annable performes the surgery, House returns to his normal level of misery (self-defined happiness).
Scenario TWO: House has some sort of brain surgery that minimises his pain. The medical 'transplant' applies to the sub plot which somehow links to House (a prisoner, someone related to Dr. Jessica Adams).
Without knowing what happens in episode 1, 'Twenty Vicodin', it's extremely hard speculating about what will happen in episode 2. That's all I have at the moment.
Any other ideas about what 'Transplant' will mean in this case?
ADDITION:
A splendid chap (aka BF) had a very interesting idea about what 'Transplant' could mean. He shared my view that it could mean House being transplanted from jail to hospital. HOWEVER, he also had the idea that perhaps there will be a case so severe that the patient will have to be transplanted to the jail hospital for House to diagnose; an illness so unusual that no other doctor can diagnose let alone cure. Then I thought that this could also apply the other way around. House could be taken to hospital (most likely PPTH) under police custody to treat the patient. That would be his first time back at PPTH. Fireworks.
