Factual error: In Sam's premonition, when Isaac is still in the bus when it is falling down to the water, he is at the front of the bus. In reality the falling force should be pushing him to the back of the bus.
Factual error: Olivia's death starts with her laser eye surgery going wrong. Why did she only have one doctor with her, and then he left her alone? In any sort of surgery, especially ones with expensive machinery she wouldn't have been left on her own, nor would the doctor be working on his own.
Answer: Bludsworth's backstory has never been addressed in the series. He seems to have an intimate understanding of the supernatural nature of death but how he knows this is never explained. Why he gives the characters advice is also never explained, however he seems to be legitimately interested in whether or not the characters will succeed in cheating death because it seems to be impossible.
