Oliver chased Talia to the western docks where she was sailing away on a small motor boat, which Oliver jumped onto.
"Talia, tell me where my son is." Oliver shouted at her.
"He's right here." Talia said as she reached into the door behind her and pulled William out and held him in a choke hold.
"Oh." Oliver said as he notched an arrow and aimed at her.
"Don't do that Oliver. As the one who taught you the true art of archery, I think we both know you don't have a shot. All it takes is one snap and I'll kill him." Talia said mockingly.
"You bitch." Oliver said tearfully.
"Language around your son Oliver." Talia said as Oliver looked like he wanted to kill her.
Oliver lowered his bow slightly before releasing his arrow into Talia's leg.
"Did you really expect to hurt me?" Talia asked.
"No, but I bet this well." Oliver said as the arrow exploded, knocking Talia back and Oliver took the opportunity to grab William and pull him into his arms.
"Are you okay? Did they hurt you?" Oliver asked.
"He'll be fine Oliver." Talia said, only to have Oliver look at her in pure rage.
"I never thought I'd come across a person I'd hate more than Damien Darhk or even more than Malcolm Merlyn. I was wrong." Oliver growled.
"Are you sure that you want your son to see you like that. After all, this was the same place where you discovered who your father really was." Talia said.
"No, I'm not to going to kill you like this. I will kill you, just not yet. Once we get back to Lian Yu, I will kill you." Oliver said.
"How do you know I won't escape?" Talia asked.
"Because considering an exploding arrow just detonated in your foot, you're in no position to escape. In fact, considering that there's a good chance your foot won't ever heal, I might just leave you here to rot." Oliver said as he punched her out.
Oliver turned to William, who looked more shocked than anything else.
"William, are you okay?" Oliver asked.
"Are you really my father?" William asked.
"I am. It's a long story that I promise I'll explain to you, but right now we need to get you and everyone else to a hospital now," Oliver said before he activated his comm link, "Laurel, do you read me?"
"Yeah, we made it off the island and an Argus chopper is inbound to get Thea to a hospital. Did you find William?" Laurel asked.
"Yeah, he's here with me. How's Thea?" Oliver asked.
"Her water broke a few minutes ago, but she's managing. Roy and Donna are with her now in the med bay and John and Rene have taken the helm and are heading away from the island." Laurel said.
"Okay, we'll meet you halfway and then I'll drop William off with you guys before I return to Lian Yu to take care of some business." Oliver said.
"What sort of business?" Laurel asked.
"Properly getting rid of Talia and retrieving Slade's body." Oliver said.
"Copy that, see you soon." Laurel said.
After dropping William off with the Argus ship, Oliver steered the boat back to Lian Yu and shoved Talia on the land, ignoring her grimaces of pain.
"Where are you taking me?" Talia asked as they approached a very familiar place to Oliver. It was the beach where he'd first signaled to go home 5 years ago.
"You miss your father so much, I've decided that I'm going to let you join him in hell." Oliver said he shoved Talia to the ground.
"Go ahead Hood, kill me so that Oliver Queen can finally be free of you." Talia said.
"No. The hood is just a piece of cloth. The darkness inside of me is a part of me and I've finally decided to embrace that. And now to finish you." Oliver said as he pulled out Talia's sword, which he had retrieved before he left the monastery earlier and held the tip out under Talia's chin.
"Like I said, I had your father in a very similar situation 2 years ago. And now I'm going to end you the same way I did him." Oliver said as he swiftly thrust the sword through Talia's heart, killing her.
"Good bye Talia. And unlike the others, you will not be receiving a grave." Oliver said as he pulled the sword of her and tossed it into the sand next to Talia.
After Oliver retrieved Slade's body and carried it back to the boat, where he then placed Slade's body in the cargo hold before going up to the helm to find everyone waiting, except for Thea and Roy, who Oliver had heard screaming in the infirmary.
"What's the status on the Argus chopper?" Oliver asked, right as something appeared on the radar.
"It looks like they're almost here." Laurel said.
"Good, in the meantime, chart a course for the nearest Argus facility and we can all get a ride home from there." Oliver said and John nodded as they heard the chopper land.
