in my view, i do no longer think of he became ever loopy. He became sane the entire time. there's a lot of diffused tricks and clues that factor to the fact he became sane. a million. which includes whilst he met Rachel Salando interior the cave, she defined to him how lobotomies (innovations surgical procedures) are completed with an icepick in the process the attention. And whilst he busted into the lighthouse close to the top and observed Dr. Cawley, the Dr. stated something like "the place are the innovations surgical procedures?" making Teddy think of he became loopy for believing there have been lobotomies occurring, yet!!!!!! interior the very end whilst he's strolling away in the direction of the nurses, you spot the nurses protecting an icepick and you spot the lighthouse, THEY CONTRADICTED THEMSELVES, they stated they did no longer do innovations surgical procedures, and Teddy made that up and it wasn't occurring, this became fake because of the fact he became top the entire time, because of the fact on the top he's going to get a lobotomy. 2. The ferry journey there. If he were there for 2 years he needless to say would have all started from the island. then what did they do? Take him out on the boat, and circle lower back around and he did no longer submit to in innovations any of this? i do no longer think of so. 3. the medicine. Rachel defined how they have been drugging him the entire time. This maximum possibly all started on the ferry, because of the fact Teddy SWORE he delivered his cigarettes with him. yet they magically disappeared? No. The drugging all started top there whilst Chuck gave him his cigarettes. this would additionally be an evidence as to why he became continuously ill in the process the action picture, and had loopy visions. AND why he became shaking a lot close to the 2nd 0.5. He didnit in simple terms start up shaking for no reason, he all started shaking because of the fact like she stated, he became dealing with withdrawls. i'm going to upload greater to this later.
