This was exactly why Emma did not want anyone to know about her relationship with Regina.
"Swan," Hook angrily grabbed Emma and swung her around to meet his eyes. "How long has this been going on?"
"What's it to you?" she retorted. "We aren't dating, so why do you care?"
He loosened his grip and his hard glare softened to one of hurt. "What?"
Emma looked confused. "Did you… think we were… together?"
"Well, yes," Hook confessed. "Usually a kiss means that."
"Oh god," Emma rubbed her temples. "It's nothing against you, you're a great guy, but… I don't think it's going to work out for us."
"I can't believe this," Hook grumbled. He began to storm away, but not before calling back, "You're making a huge mistake."
Emma rolled her eyes, and turned back to a very awkward-looking Regina. "Sorry you had to witness all that," she apologized. They started walking towards Emma's car.
Regina laughed. "Oh that was nothing, you should have seen Robin's reaction." Her smile fading, she continued, "But about what you said- about other people knowing about us- we really need to keep that to a minimum. I don't know what the reactions of everyone will be if they find out about…us, and as the mayor, I need to be respected by everyone. I can't let their opinions of me take away from that respect."
Emma nodded as they stopped in the parking lot. "Of course. That's why I said that. Finding out that I'm with you, of all people, the one who hated me for the longest time is sure to stir up some mixed feelings from everyone, and I want to avoid that."
"You never got to finish your drink… Why don't we go back to my place?" Regina suggested.
"Sure, hop in," Emma grinned. She started the old yellow car which groaned in protest but sorely complied, and they drove to Regina's mansion of a house. There was a pause. "…Is Henry home?"
Regina laughed and raised a dark eyebrow at her remark and turned towards the blonde. "Are you implying something?" she replied in her sultry voice.
"What?" Emma quickly realized how that could have been misunderstood, and she blushed furiously. "Not that. Sorry. I was definitely not trying to say we should do that- I mean, unless you want to…" She shook her head to stop babbling. "I was just thinking, should we tell him yet?"
Regina laughed at how obviously embarrassed Emma was. "I was only kidding, dear. And no, he is not, he's staying at a friend's house for the night. But I think we should wait just a little longer- we can't have him telling anyone at school, now."
Pulling in the long driveway, Emma agreed.
"Well, shall we go in?" Regina said after a short silence. The pair got out of the car, and entered Regina's massive house. Emma sauntered into her living room and flopped down on a couch. Regina entered with two drinks in hand and sat down beside her new girlfriend with a kiss.
