I'm not entirely sure, but I think they would kinda look good together, they are both tall and if I'm not mistaken most funny things happen between them.
For ex: Prentiss
physics magic
"he's so lifelike." ( poke )
"are you considering having little baby geniuses."

Reid :
"I can't believe there was a time this was socially acceptable." ( talking about Prentiss's high school yearbook pic.)

this one,or Hotch&Emily,my 3 choice had be Reid&Garcia:D

Hotch & Emily all the way! hehe.

Cute!

Morgaan and Garciaa are so cute.
Then Hotch and Emily that would be sweet.
Reid and Emily is just wrong; she is 14 years older.
No thankyou.

Emily and Morgan
No ONE TOUCHES REID!!!

otp.

WHERE IS REID AND JJ!?!?!?!

they have been very flirty lately:)

In adorableness terms Morgan and Garcia but I would most want Hotch/Prentiss *sigh* never gonna happen though.....

I would always pick them♥:)
