Captain Olivia Benson (Mariska Hargitay), Sergeant Odafin “Fin” Tutuola (Ice-T) and Detective Joe Velasco (Octavio Pisano) serve as witnesses to the big moment for their friends and SVU colleagues.

Velasco smiles at an emotional Benson as she warmly holds her hand over her heart (balancing out Fin’s characteristically stoic stance).

Fans have been wondering for months about how Rollins and Carisi’s storyline would wrap, especially after the description for this season’s fall finale, “And a Trauma in a Pear Tree,” mentioned the two working on an “important arraignment.”

“You gonna start crying already, Liv?” Fin quipped in the clip.

“I love you, Amanda,” a choked-up Benson said as she and Rollins embraced.
