OK, so I have two characters, and they are very snappy to each other (as they are to everyone) and yet I'm planning a romance between them that hasn't emerged yet.
Here's a little bit of conversation between the two after the girl became sick and the boy is acting as her caretaker:
I woke up to Thomas staring at me from a chair across the room. "Go away, I'm fine," I snapped. He replied with "I'm sorry, do you have memory loss as well? Because last I checked, you couldn't stand," I glared at him. "Why are you still here anyway, I'm pretty sure all I've been so far is rude" I asked. He shrugged "I like being close to you," he said.
It's actually pretty far along in the story, and Thomas' statement "I like being close to you" comes dangerously close to exposing the truth. How do I tell when (now, a bit later, or much later) to bring it out into the open.
