David Rossi gets a birthday gift he certainly didn’t ask for in this exclusive clip from tonight’s Criminal Minds (CBS, 9/8c).

In the Season 12 episode titled “Profiling 202,” Rossi (played by Joe Mantegna) is at home winding down his special day when he gets a phone call from serial killer Tommy Yates (played by Adam Nelson), a longtime nemesis who in the Season 7 episode “Profiling 101” negotiated away a death sentence in trade for annually disclosing the location of one of his many victims.

Typically, that intel comes via a prison visit from Rossi. Except now Yates is on the loose — and he has a second surprise to spring on his old foe, after delivering a few haunting, discordant bars of “Happy Birthday to You.” Press play above to find out what that twist is.
