Edward speaks in awe of Carlisle’s transformation, explaining, "It’s a miracle he was able to keep silent, to stay undiscovered," (TW15) due to the agonies he would have endured. Carlisle’s conversion would have been particularly painful because "his bites were not deliberate 또는 well placed," (PC8), therefore it took a little 더 많이 than three days to become a vampire. The pain is so bad that for "every minute" of the transformation, "a victim would be wishing for death." (TW20)
Alice is unusual in that she cannot remember her transformation at all. "She didn’t even seem to notice the pain, poor little creature. She’d been stuck in that black hole of a cell for so long." (TW22)
The transformation process is simple, assuming the vampire doesn’t drain the human body of blood. A human is bitten, and the venom is allowed to spread for a few days. The actual length of time a transformation takes is dependent upon "how much venom is in the bloodstream, how close the venom enters to the heart." (TW20). The venom is pumped around the body as the 심장 keeps beating, and various physical changes occur as the poison moves. One of the changed that happens is the body’s "healing" (TW20) from the injuries that may have occurred to it, such as Emmett’s mauling 의해 the bear.
"The greatest pain begins when the venom is all the way through the body, through the heart, and it starts meeting itself in the veins again and then burning them dry. It moves slower than blood because it’s thicker. Each beat of the 심장 can only push it so far. The changing/burning process is slow. The venom has to leak through to every cell before it ends." (PC8). The final stage in conversion happens when "the 심장 stops"(TW20), at which point the human becomes a vampire.
