Ernesto eventually took Hope prisoner and held her hostage in a cave.
The cave exploded before Bo’s eyes, leading him and everyone else to believe that Hope was dead.
Bo returned to Salem to raise his son as a single father.

At the time, Bo and Dr. Carly Manning (Crystal Chappell) didn’t like each other.
They often butted heads and seemed to have very little in common.
Bo and Carly eventually bonded as well over Shawn, and she began to develop feelings for him.

Bo and Carly eventually began dating and fell in love.
However, Bo’s love for his late wife Hope stopped him from making a commitment to Carly.
Carly and Victor’s relationship eventually fell apart and she and Bo reunited.

While in Mexico, the two had a symbolic Mayan wedding ceremony.
The two fell quickly for one another and got engaged.
Gina had no memory of ever being Hope or her friends and family in Salem.
However, she came between Bo and Billie as Bo was obviously drawn to her.
Sadly, their love story ended when Bo died in 2015 (viaSoaps).
