Jane Lynch plays Diana Reid, Dr. Spencer Reid's mother
Spencer Reid was created in 2005.
There's been some speculation as to the relationship of Spencer and Seaver, but nothing's been confirmed yet.
Dr. Spencer Reid has an eidetic memory, which is often or commonly known as photographic memory.
Dr. Spencer Reid is most obviously attractive. The actor, Mathew Gray Gubler, that plays Reid is neat. You should see his fan-pages and the comments of his pictures on Facebook. : )
As Reid himself has stated before, he is not a medical doctor. In fact, the main reason he is introduced as "Dr. Reid" throughout the show was because Gideon feared that Spencer would not be taken seriously otherwise since he was so young at the time.
Dr. Reid does not currently have a girlfriend, although he shared a kiss with Lila in the episode " Somebody's Watching" season 1 episode 18
obviously
He first appears in Dr. Reid's first drug induced flashback in "Revelations." (2x15). His present appearance is first seen in "The Instincts" (4x6) during a dream Spencer has near the end of the episode. His first physical appearance is in "Memoriam." (4x7).
It is unknown if the actress who played Lila will ever return. The character has been mentioned before though.
Its is unknown but his mom does.
