I have always felt that Gendry has some important role to play regardless of his status as a bastard. This is primarily motivated from RNS Entertainment's video. Look it up if you want, and I hope you enjoy it (video and my story).

She screamed already for hours, he wish he could take the pain away from her. Robert was gone hunting when the contradictions started and now it was only him with master Pycelle in the bedchambers of his sister, who was giving birth. The baby had a big head, or that was what Pycelle said. He didn't care, he just wanted it to stop, the screaming, the pain of his sister, she didn't deserve this. The man who got her with his child wasn't even here and now he was here to help her get through it. Through everything. Cersei hated the marriage, not at first, but after the first wedding night she started to resent him, the drunken fool. He couldn't even appreciate what he had.

Finally the screaming stopped and he wiped away the tears of her face. Then he knew something was wrong, it was silent and Cersei noticed to. She sat up and looked at Pycelle who hold the cause of her pain of the last couple of hours. "A baby boy. He still lives, but it's unusual that he makes no sound, it means that something is wrong. I'm sorry your grace."

Cersei didn't even flinch or cry, she just hold out her hands to hold the boy. It looked now so small, with thick black hair. Cersei hold him to her, but he did noting, just staring at her with blue bright eyes. He was clearly Baratheon in looks, but he was also a Lannister. She didn't do anything, just looking at the quiet boy, who was staring straight back. He didn't even cry for food.

The small boy looked up at her in wonderment, his pink mouth hanging open as if to talk, his blue eyes the widest she'd ever seen. He was beautiful. She wanted to love him. She could look past the Baratheon features and raise him as a lion. But the resentment for Robert was a bitter and vile taste in her mouth, ever present. She could not look at the boy without seeing Robert, the man who made Cersei shrink into this. This hating, angry, upset and vile being.

Robert then came into her chambers with a stag pelt clutched in his arms. His eyes then turned to the small bundle she was holding in her arms. "He's perfect," her husband finally said, the first words she'd heard from him in several hours. "Our little stag." He reached out a finger and the boy instantly wrapped his tiny hand around it.

"And a lion," Cersei whispered, tears stinging at the back of her eyes.

"Aye." Robert's eyes never left the babe. "He looks just like you." What sort of things was he speaking of? But looking into the babe's pudgy face, she saw that he had her nose and possibly her father's jaw. And looking closer into his eyes, she could see tiny specks of the Lannister emerald green eyes within the Baratheon ocean/sapphire blue eyes.

"Have you picked a name for him?" Robert asked. He should have the honour of it. After all, she just went through one of the most horrible experiences she may had endured ever. It would practically be a boon for him to name his heir.

"No. Do you wish to name him?"

"Well, he's a Baratheon. Clear as day. How about Orys?" he said to the babe.

He then made a small gurgling noise and scrunched up his face a little. Silent as he was, he was quite responsive. He must not have like the name his oaf father picked out for him.

"Perhaps we should name him later"
