A word for: something good that came out of something bad [duplicate]

I need a single-word to describe something good that (unexpectedly) resulted from something bad. This good thing could not have occurred without the bad event happening first, as a precursor.

Example sentence: "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the ____," (something like that).

silver lining

"I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the silver lining"

From Wikipedia

A silver lining is a metaphor for optimism in the common English-language which means a negative occurrence may have a positive aspect to it.

Etymonline says:

a "bright side" which proverbially accompanies even the darkest trouble; by 1843, apparently from oft-quoted lines from Milton's "Comus," where the silver lining is the light of the moon shining from behind the cloud.

Was I deceived? or did a sable cloud Turn forth her silver lining on the night? I did not err, there does a sable cloud, Turn out her silver lining on the night And casts a gleam over this tufted grove.

To which Thomas Warton added the commentary: "When all succour ſeems to be lost, Heaven unexpectedly presents the ſilver lining oſ a ſable cloud to the virtuous."

Serendipitous. Adjective.

I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was serendipitous

Wiktionary says:

combination of events which are not individually beneficial, but occurring together to produce a good or wonderful outcome.

The idea behind serendipity (its noun form) is that a beneficial outcome emerges from one or more chance events. Your example speaker didn't choose to get in an accident, but that accident led to falling in love. Another example: a romantic comedy like Pretty Woman may have plenty of misfortune but it has a serendipitous outcome: two people fall in love.

One phrase associated with serendipity that seems especially applicable to your example is "happy accident," one translation of felix culpa.

noun: blessing in disguise

an apparent misfortune that eventually has good results
