-Drinks all of the coffee

It’s like a competition when it comes to caffeine consumptiom with these two. They’ll work for hours with only coffee and energy drinks as fuel, and they won’t notice how exhausted they are until they either finish whatever they’re working on or pass out from fatigue.

-Brings up adopting a pet

It was sort of mutual. With all their responsibilities and whatnot, neither of them have any interest with going to the pet store and being all domestic like that, not without a scientific motivation. They’d probably get a lab rat or two, some test subject animal, and overtime, it’d be like a sort of bonding thing spending time together taking care of and studying this/these animal(s) for hours, days.

-Kills the bugs

Holiday. Caesar is very strict about his workspaces, especially when he’s really focused. Of course, Holiday agrees with keeping things from being contaminated from insects and etc., Caesar, of course, can’t do anything like a normal person and has come up with some creative but incredibly unnecessary ways to get rid of a big that’s resulted in multiple fires, one quarantine, and several lectures about work safety and the use of money on “more efficient fly swatter technology”. Holiday just uses a shoe or something which saves time and lives.

-Cooks the meals

Caesar. As smart and skilled Holiday may be, it’s best to keep her away from the kitchen if you want to eat something edible. Fortunately, Caesar is a surprisingly efficient cook.

-Starts getting into holidays way before they should

More likely to be Caesar. Not because he is super fesitve about holidays, but he just has a crap sense of time and starts planning and buying things much too early.

-Initiates the couple selfies 

Neither are interested in taking selfies, but Rex would probably be the one who would want to capture moments. Caesar and Holiday would both do it to humor him.

-Forgets the birthdays and anniversaries

Caesar, without a doubt. Absentminded and work-oriented, yearly celebrations are the last thing on his mind. Though, he has to keep a strict collection of alarms and reminders unless he wants a peeved Holiday at him for weeks again.

-Always ends up with too much junk food after grocery shopping

Caesar. He has no impulse control. Holiday has to be his impulse control. Her motherly responsibilities are never done.

-Nicknames the other
