Glass House RatingsThe cracks are starting to show in The Glass House (1.2/3). The second week of ABC’s legally contested reality show was down 20% from its June 18 debut, which scored a 1.6/4. Opening ABC’s night at 8 PM, The Bachelorette (2.2/7) hit Prague but stumbled, down 4% from last week. That ties a series low for the search-for-love series.

Laying more groundwork for its Olympics coverage from London this summer, NBC had the U.S. Olympic Trials: Swimming (1.9/6) live from 8-9 PM. The network’s America’s Got Talent (3.0/8) rose 3% from last week, making it the No. 1 show Monday among adults 18-49 and total viewers with an audience of 10.41 million. NBC’s American Ninja Warrior (2.0/5) was flat with last week and tied — except for specials — its season low.

A bit of simmer on Fox’s Hell’s Kitchen (2.3/7) as the Gordon Ramsay series was down 8% from last week. At 9 PM, MasterChef (2.2/6) slipped 4% from last week. CBS had a night of repeats with How I Met Your Mother (1.1/4), 2 Broke Girls (1.3/4), Two And A Half Men (1.3/4), Mike & Molly (1.2/3) and Hawaii Five-O (1.2/3).
