Carlos' (Jeffrey Vincent Parise) worst fears may be coming true on General Hospital, as he learns that the woman he loves could be in a life-or-death situation.

Ava Threatens Carlos

While out, the car Sabrina (Teresa Castillo) was in with Patrick (Jason Thompson) and Emma (Brooklyn Rae Silzer) was run off the road and is perilously hanging and about to fall into water that is charged from a downed electrical wire.

Carlos has been in fear of Sabrina being hurt since Ava (Maura West) threatened to harm her if he told the truth about A.J. and Connie's deaths. Now, it appears she could have made good on the threat, sending Carlos into a panic.

Sabrina's Life Threatened By Ava?

"Wait a minute, what about Sabrina?" he yells in a preview clip for the Thursday April 24 episode. He is still in the jail when he learns of the accident and is panicked because while behind bars there is nothing he can do to help her.

He is not the only one worried in Port Charles, as others are affected by the potentially awful condition Patrick and Emma could be in as well. Anna (Finola Hughes) is especially worried about her granddaughter.

"Is she all right?" she asks Nathan (Ryan Paevy).

"I don't know," he says.

The two boys who are both in love with Emma are also worried, and though they are currently enemies as they compete for her heart, Spencer (Nicholas Bechtel) will confide in Cameron (Michael Leone) over his worries.

"Emma is in real danger," he says.

General Hospital airs Monday-Friday at 2 p.m. on ABC.
