"I don't want to be weak. I want to be strong."

Dr. Lilliana Hotchner (neé Reid), nicknamed and often called "Lily", is a Supervisory Special Agent with the BAU. She is married to Aaron Hotchner, her unit cheif, and is the fraternal twin sister of Spencer Reid. She, alongside her brother, is one of the youngest members of the BAU.

Lily is hailed as a genius and autodidact. She has an IQ of 192 and can read 40,000 words per minute with an eidetic memory. She has acheived has five PhD's, three MA's and seven BA's, allowing her to specialize in many areas of knowledge. However, Lily specifically specializes: statistics, geographic profilings, terrorism and counter-terrorism.


Lily was born on October 9, 1981. From a young age, it was obvious that she and her brother were both gifted children, as the both of them were a genius and autodidact. In her youth, her father, William Reid, left her and Spencer along with their mother, Diana, as he could no longer deal with Diana's schizophrenia, among other things. At the age of twelve, she and Reid graduated from a Las Vegas public high school.

Following her graduation from high scool, Lily and her brother both were accepted to Caltech. Lily studied at Caltech long enough to acheive her PhD's in Mathematics, Chemistry, and Engineering, as well as her BA's in Psychology and Sociology. When she and her brother were recruited to join the BAU by Jason Gideon, Lily turned down the offer. She wanted to continue studying at different universities to acheive more PhD's and BA's, as well as MA's.

She was often the victim of bullying in high school, being teased and humiliated by other girls. Lily once mentioned that she was asked to a school dance by an older boy she had a crush on; however, when she showed up to the dance, he already had a date. Then when she tried to leave, she had a mix of mustard, honey, and feathers dumped on her in front of everyone at the dance. When she returned home, her mother didn't notice or ask what had happened, and instead Reid comforted her and helped her clean up.

Lily grew up learning nearly everything she knows from books, with her mother (a college professor of 15th-century literature) often reading to her and Spencer. Still, Lily knew that the way her mother was living wasn't healthy.

When she and Spencer were eighteen, they had Diana placed in a mental institution. She still resides in that same mental institution and Lily has stated that she sends letters every day because of the guilt she feels for not visiting her. Lily is also worried about the fact that her mother's illness can be passed on genetically; she once told Hotch that, "I'm afraid... I'm waiting for my own mind to turn on me."

Lily, like her brother, has an eidetic memory, meaning that she can remember an exceedingly large amount of information with extraordinary detail. This, however, only definitely applies to information gathered visually (especially things she's read, as implied with the word eidetic). Her ability to retain auditory information, however, has been rather inconsistent. This is evident when she once stated that she can't remember the name of "Penelope's new boy-toy".

Lily has been shown to be very good at remembering speeches, even those in a different language which she can't even speak.

Personality Edit

Lily is socially awkward and sometimes shy. She can often be withdrawn from others, especially those who make her comfortable or she doesn't like. She has been known to fixate of things - prompting Morgan and the other team members to tell her to be quiet - and misses social cues at times. When she is forced into an uncomfortable situation, she will use statistics and facts as a defence. 

In rare moments, Lily has been shown to doubt herself and have low confidence. This is a result of the severe bullying she suffered in high school. Despite this, Lily is very protective and caring. She is willing to put herself into dangerous situations to protect the people she loves.

Lily, like her brother, is an eccentric genius with hints of Schizophrenia and minor autism (Asperger's Syndrome). Lily is also germaphobic. In general, she dislikes shaking hands, and shows adverse reactions when touched by strangers. Lily also has a slight case of obsessive-compulsive disorder, shown whenever she straightens the files and papers in the conference room when in a briefing. While Lily s concentrating, she likes to fidget around with objects, as it helps her concentrate.
