LiarsSomebody is supposed to die on tonight’s summer finale of “Pretty Little Liars” (Freeform, 8 p.m.), which comes on the heels of the announcement Monday that the show will end after its upcoming seventh season.  It’s the end of the summer episodes for “Dead of Summer” (Freeform, 9 p.m.) also reaches its finale.

Oftentimes “The Bachelor” and its spin-offs operate around the craziness of just one character. On “Bachelor in Paradise” (ABC, 8 p.m.), it’s definitely Ashley.
