On Monday's Crazy Ex-Girlfriend, Rebecca (Rachel Bloom) does what she does so well - self-sabotage - but this time, not with Josh (Vincent Rodriguez III). Having distanced herself from her long-unrequited love Josh (just when he's realizing he has feelings for her), she's making the seemingly wiser decision to give Greg (Santino Fontana) a go.

This almost seems like a healthy choice, given Greg's relative maturity and noble acceptance of her eccentricities — until, that is, they hop into the sack for no-strings sex. They make a pact to tell no one in their circle, and spend days ravishing each other. They're convinced they can "just" have sex despite their history, which is essentially Rebecca running to Greg whenever Josh didn't seem attainable.

Naturally, this leads to crises — and not just one of Rebecca's hilariously pitiful breakdowns either, but a real-deal actual medical emergency brought on by so much great sex. Suddenly, their down-low hookups are at risk of becoming exposed, putting both of them in jeopardy of losing what they actually want.

Crazy Ex-Girlfriend airs Monday at 8/7c on The CW. (Full disclosure: TVGuide.com is owned by CBS, the parent company of The CW.)
