Thea could also be a great godmother. She's Oliver's sister and has grown a lot. She could be there to spoil the baby and also teach it some important lessons about family and loyalty.
A possible plot is that Felicity discovers she's pregnant at a very inconvenient time, like right in the middle of a major battle plan against a big villain. This could lead to a lot of internal conflict for her and Oliver as they decide whether to continue with the plan or focus on the pregnancy. Also, they could face challenges in preparing for the baby, such as finding a safe place to live considering their dangerous enemies.
The kiss could be described in various ways in fanfiction. Some might focus on the physical aspect, like how soft their lips were, the warmth of the moment, and the electricity that passed between them. Others may emphasize the emotional aspect, such as the relief of finally expressing their feelings, or the fear of what this new step means for their future. It can also be a way to show character growth, especially for Oliver who might be opening up more because of Felicity.

They could also face challenges in raising the baby while still being vigilantes.
One popular trope is 'Enemies to Lovers' in a way. At the start, Oliver was all broody and Felicity was this bright, bubbly hacker.
