In Rude Awakenings, Sam spends most of the episode trying to prevent "Quinn" from being called back undercover. He tries to drown CIA Agent Snyder (Sabatino's partner, the one who gets shot in Wanted) because Snyder has been cavalier about Michele's safety. In Wanted, he breaks out of jail to interfere in an already planned operation, to protect her. In Descent, he again tries to prevent Quinn from getting involved by pointing out that they don't know if Sidorov made Michele; Granger has to point out to Sam that the mission comes before any agent's individual safety. In Ascension, Sam breaks out of the hospital, but when he finally catches up to Sidorov on the hotel roof, he can't take the shot (even though he had backup from Kensi) until Deeks charges through the door and shoots Sidorov's assistant.
Yes, very cucumber-like.
