Had anyone else been around to hear, he would be embarrassed. Aden was many things- sarcastic, standoffish, rather volatile even at the best of times. Individualistic, definitely. While he certainly could be merciful and even kind, it wouldn't be most people's first choice in describing him. But with Vector... Vector made him want to be a better person. Aden couldn't say that about anyone else.

So even if being openly loving was rather embarrassing when he was so used to being prickly, Vector was the only one deserving of seeing this side of him. Loving, affectionate, and open about how he was feeling and the love he felt.

"Now and forever... I like the sound of that," He said, looking up at him with a genuine smile, and with genuine affection, and he reached to put his hand over Vector's, "I feel the same. Yours, now and forever. Only yours."

Sleeping around was something that might have just seemed like a quirk of Aden's being. On every planet, and on nearly every mission, he'd ended up in someone's bed, come slinking back to the crew afterwards... But now? Now he had Vector and he was happy to be only his. He didn't need anyone else.
