Brad Cooper's return to Port Charles will shake up several characters on General Hospital

Whose life will Brad upend?

Brad Cooper (Parry Shen) will soon return to Port Charles on General Hospital. Fans had been anticipating this news since Britt Westbourne (Kelly Thiebaud) was revealed to be alive.

When Selina Wu (Lydia Look) was shown in a flashback with Curtis Ashford (Donnell Turner), this gave GH viewers even more hope that the lab tech was headed home.

The question is, who will Bradly cause the most trouble for when he hits Port Charles? He gave Drew Cain (Cameron Mathison) the blackmail info on Portia Robinson (Brooke Kerr) in exchange for a lot of money. Could he now decide to cause problems for one or both of them?

Could Brad have a target on his back?

Brad left town with several million dollars, but is he still financially stable? He might have gone through the money and needs a job. Would he attempt to return to the General Hospital lab, and would that put a target on his back? Drew might come after him as well as Curtis, on Portia's behalf.

Portia might confide in Isaiah Gannon (Sawandhi Wilson), who may give Brad a warning on behalf of the woman who might be carrying his baby. Some GH viewers were hoping Brad would begin working with Selina in the family business and show his more ruthless side.

There is also a chance that he and Britt might get into mischief together. Would she confide in him what has been going on in her life, or will she continue to lean on Jason Morgan (Steve Burton). The biggest question is how Brad's PC return affects Lucas Jones (Van Hanis).

He knew about Lucas and Marco Rios ( Adrian Anchondo), but probably assumed it was nothing more than a fling. Marco and Lucas are living together at Wyndamere, but fans know this will not last long.

Marco is involved with his father, Jens Sidwell's (Carlo Rota) nefarious business dealings. He is also aware that his dad has murdered several people.

Could Brad and Lucas reunite?

Once all of this comes to light, Lucas will be shell-shocked and realize Carly Corinthos (Laura Wright) was correct that Marco was in cahoots with his dad and would hurt her brother. 

Carly doesn't want her brother with Marco, but she also has reservations about Brad. _Perhaps she should stay out of Lucas's affairs, considering how many times she returned to Sonny Corinthos (Maurice Benard).

Will Brad be there to pick up the pieces, and is there a chance he and Lucas will reunite? Perhaps something will escalate during February Sweeps, but until then, there is no way to know for certain.

Trouble follows Brad

Lucas values honesty, and Brad has lied to him many times, which is how he blew hsi last chance at reconciliation. Still, he might decide that his ex-husband is the lesser of two evils because Cooper has not been involved in covering up any murders.

Could Brad end up with a target on his back and Sidwell decide to take him out because of hsi connection to Britt? Perhaps Marco will do something deviant because he feels threatened by his boyfriend's former spouse. Stay tuned to General Hospital to learn what happens next with Brad, Britt, Lucas, and Marco.

Paarry Shen spoke to Soap Opera Digest but did not reveal any details on his General Hospital character's return. He also did not indicate whether he will be on contract or how long his character will remain in Port Charles.

What is certain is that Sidwell and Marco will be exposed, and Lucas will be brokenhearted. What will happen with Brad is anybody's guess, but fans know trouble follows him so stay tuned.
