a timesphere, you have my attention. but!! he sounds absolutely adorable and exactly like the kind of person tati probably got pretty fond of him pretty quick? she's a very focused, hbic type but working in pr, she's obviously charming (even if it's sometimes superficial/in a surface level type of way) and adept at adapting to her surroundings and the people she's with. she's one of those people that's sort of vaguely versed on a lot of different topics specifically so she can carry on your typical small talk high society socializing so once she honed in on him being a science-y type she definitely would've struck up a conversation before it inevitably went waaaay over her head! luckily she's all about learning even more, so she wouldn't have been mad at all about going on and on about flux capacitors. she's generally sweet, if a little hard to read and comes off as kind of intimidating at first blush.
