Blaine is going to be taken from about 20 years in the future and he'll be around 50 years old. During that time he became an adoptive father when his mentor and lover died ten years ago and left him a surprise son. The mother also died and so Blaine procured himself a two-year old [who is 12 when Blaine is pulled from canon again]. Aside from freaking the hell out, he matured and settled down a lot more than he might've with only obligations to the Org and Family. He's still a bit sarcastic, but for the most part he's calm and doesn't tease or try to get a rise out of people like he used to. He flirts, but he isn't in your face about it. He a mature adult...!
