Criminal Minds, Season 2

[Reid is sitting alone after unintentionally telling Garcia that his mom is institutionalised. She gets close to him.]

Garcia:
She's ok. Your mom. They just picked her up, she should be at the airport by now.

[Reid takes the Valentine poem his mom read to him and that the Fisher King sent]

Reid:
I forgot she used to read me this poem [smiles], it's funny, hah.

Garcia:
Funny?

Reid:
I should've realized this sooner. Nobody knows the fact that JJ collected butterflies except for me. People tell me their secrets all the time. I think it's because they know I don't have anyone to betray them to. Except my mother. I tell her pretty much everything. [Laughs]

Garcia:
[smiling] I don't think anyone would mind

Reid:
Did you know that I write her a letter everyday?

Garcia:
That's nice

Reid:
Depends on WHY I write her

Garcia:
What do you mean?

Reid:
I write her a letter so I won't feel so guilty about not visiting her... [looks down] Did you know that schizophrenia is genetically passed?
