## A sinkhole, then a volcano

ABC's 9-1-1 returned for its 10th season on Thursday, Oct. 15, with a premiere titled "That Sinking Feeling" that puts a volcano in the middle of Los Angeles. The episode aired at 8 p.m. ET, ahead of the Season 2 premiere of 9-1-1: Nashville and the Season 23 premiere of Grey's Anatomy, according to TVLine and TechRadar.

According to recaps by TheWrap and Hidden Remote, the 118 firefighters respond as a huge sinkhole opens in the city during a multi-vehicle emergency. TheWrap reported that the crew, led by Chimney, got everyone out without major casualties. The hole keeps growing, tremors follow, and lava shoots out of it at the end of the hour. TheWrap quoted Hen's closing line: "That's not a sink hole. That's a volcano!"

Both recaps describe Maddie spotting an increase in emergency calls from the area around the sinkhole in the days before it opened, and being assigned to review those calls for a pattern.

## Athena's first detective case

Athena Grant, played by Angela Bassett, starts the season as a detective. TheWrap and Hidden Remote both report that her case begins with an injured man left outside a hospital and leads to a jewelry store where robbers had dug a tunnel. The episode ends with Athena underground in that tunnel as the ground shakes.

## Buck as a parent

Oliver Stark's Buck is raising his toddler son Theo. In the premiere he ends up in the emergency room with a facial injury, which TheWrap described as his fourth non-work ER visit in three months. At a dinner at Eddie's house, Theo knocks Eddie's son Christopher down, and both recaps say the incident leaves Eddie unhappy with Buck's parenting.
