9-1-1 on Fox at 8:00pm ET.
Bachelor in Paradise on ABC at 8:00pm ET. It seems hilarious to me that this is on ABC main while Dancing With the Stars, the go-to cultural rehabilitation for assholes of various stripes, has been shoved over to Disney+. Apparently, we as a nation prefer watching reality show contestants drink and yell at each other near a beach rather than attempting to dance.
NCIS on CBS at 9:00pm ET.
No One Can Hear You Scream on Investigation Discovery at 9:00pm ET. Series premiere. This is another murder show, one where the murders/almost murders happen somewhere in isolated areas.
The Vow on HBO at 9:00pm ET. Second season premiere. More about NXIVM.
