Ear Keloid
The Ear Keloid, also known as the rotting ear, is a keloid which Dylan developed on his ear that has continued to grow in size due to his neglect.
While it's exact date of origin is unknown, it is speculated to have begun growing as early as January of 2018. The exact reason as to how it may have began to grow is also unknown. However, widely supported theories suggest that the keloid began to form as a result of a botched ear piercing which later became infected and grew into a necroing mass.
Dylan has been questioned many times from many sources as to the reason why he has neglected treating the mass. One common reasoning is that he is not able to afford it due to his finances. He has claimed that doctors have deemed the keloid surgery as being purely cosmetic, and thus not being covered by health insurance.
The current status of the keloid at any given point is unknown, however it is unlikely that Dylan will get rid of it unless it poses to be life threatening.
