Glenn Donovan is the ex-husband of Tracey Donovan and father to her three sons. Played by Bob Cryer, Glenn made his first appearance on 15 August 2017 (initially played by Neil Roberts, prior to being recasted).
Glenn made his first appearance upon Darcy texting him, requesting to meet him at a bar: whilst it is made clear that they are not on good terms (he insists she deletes his number), Glenn is credited only as "Darcy's Mystery Man".
Prior to his arrival, it was mentioned that Glenn partially drove Tracey to alcoholism, due to his affair and the separation that followed. According to his stepdaughter, Grace Black, she "met him when [she] was nineteen and then he took off".
His arrival in Hollyoaks infuriates Grace, who resents Glenn for what his impact on her mother. Regardless, he attempts to win her trust ('rescuing' her from Warren when he is seen attacking Grace), but is repeatedly told to stay out of her business. Glenn takes her home and coaxes her into talking about her grief - where she eventually breaks down in his arms. Glenn orders Grace to take some time to grieve, and takes over her plan to assist Sienna in escaping the village. He finds a safe-house to accommodate Sienna in; this backfires, however, when Warren finds her.
When Glenn discovers that Darcy Wilde killed Tracey, he orders her to go to Germany. She refuses, and shocks him by admitting that Toby is Glenn's son (as opposed to his son, Adam Donovan's). He agrees to keep her secret on the condition she helps him re-connect with Adam.
Grace continues to berate Glenn for his saviour complex ("Saint Glenn to the rescue again!"), and we learn that his affair was with a teenage Grace.
Glenn catches on that someone was grassing him up unaware that It was his own son Adam Donovan but was led to believe It was Trigger when Glenn's girlfriend Grace Black told Glenn It was Trigger who In fact grassed him up after Glenn gave Maxine Minniver 20,000 pounds to let Trigger prove that it was not him who grassed him up Glenn got Trigger to get the money back for Glenn and he did this knocking Maxine out and making her go to hospital despite Trigger doing what Glenn told him Glenn still believe It was Trigger who grassed him up so he drew his gun and shot Trigger dead (Off Screen) he later shows Adam the body and got him to bury It Adam later made Shane Sweeney confess to the murder of Trigger after his body was found by the police thanks to Adam.
Again, Glenn catches on that someone is grassing him up to the police still unaware that it is his son Adam Donovan only this time he thinks that it is Zack Loveday so Glenn gives Adam a gun and instructs him to kill Zack and the two plan to kidnap him, When Adam decides to let Zack go Glenn finally catches on that Adam is the one who has been grassing him up to the police so Glenn draws his gun and points it to Adam, Adam now scared, Glenn shoots and kills him Zack hears the gun shot but continues to run.

He is the only person who knows Glenn shot Adam.
