Among the calls the 9-1-1 team responds to in the new episode "A Little Help From My Friends" are a bloody disaster scene at an ice cream shop and a little boy who has gone missing from his own birthday party. Elsewhere, the EMTs stage an "intervention" for Owen (Rob Lowe) after he accidentally blurts out his secret to Mateo (Julian Works), his new roommate. Later, T.K. and Carlos (Ronen Rubinstein, Rafael Silva) take a major step in their relationship. Sierra McClain also stars.
