I'm not sure specifically which 'cliffhanger not alone' you are referring to. It could be a story, a movie, or something else. Maybe it's about a person in a cliffhanger situation but not being alone, perhaps they have a companion or some form of support during a difficult or suspenseful event.
Well, without more context, it's hard to tell the full story. 'Cliffhanger not alone' could imply that there's a character in a precarious situation like hanging from a cliff, but they are not solitary. There might be another character involved, like a friend or a rescuer. It could also be a metaphorical cliffhanger in a non - physical sense, where someone is in a tense situation but has someone by their side.
The phrase 'cliffhanger not alone' is rather ambiguous. It might be part of a thriller story where the main character is in a cliffhanger situation, for example, trapped on a mountainside. But they are not alone, which means there are other elements at play. There could be a hidden motive for their not - being - alone status. Maybe someone is using their situation for their own gain, or perhaps it's a story of true friendship where the companion is there to selflessly help the one in the cliffhanger situation.
