JJ stands with the rest of the BAU, waiting for the s-x crimes unit to show up. Talking over the case they’ll be working on them with. When they finally do show up, JJ’s eyes immediately go to the woman leading them. She looks a lot like Reid, looking at the two of them. She notices a tattoo on the girls wrist- a heart with Ohana in the middle, surrounded by the names Spencer and Diana and realizes this must be Spencer’s sister. She'd heard about her, but she can't believe she's actually meeting her now.

And she's so cute.
