Since its first episode aired in 2012, “Catfish: The TV Show” has held up a mirror to our online lives, reflecting how we present ourselves and make sense of love, lust, trust, companionship and loneliness in an increasingly digital world. Each episode unfolds like a detective show, with the host Nev Schulman summoned to untangle truth from lies, to take relationships that exist only on computers and phones and drag them into our three-dimensional reality. The saga of Danny and Jose, which aired in 2017, is emblematic of the deception, dashed hopes and complicated situations regularly featured on the show.
