Hey guys, I'm officially back! So there isn't much content for Malcolm, and we don't know a ton about him but I had some ideas so I figured I'd share! If you don't know who I'm talking about, he's a son of Athena and he was kind of Annabeth's second-in-command until she left CHB and he became head counselor.
Much like he's the first person to notice Annabeth and Percy's feelings for each other, Annabeth is the first to notice his feelings for you. She would often push him to "go for it!", much to Malcolm's irritation.
When he's nervous or flustered he'll cover it up by spouting random facts that pop into his head. You think he's just smart and offering you information, but Annabeth knows what he's doing. He can't hide it from her.
Malcolm is very used to things being linear, so he tries to study you and figure you out for a long time before eventually learning that you aren't numbers on a spreadsheet. You're a person, and people are strange and colorful and unpredictable.
He learns to love that.
He's super uptight. Being Annabeth's second-in-command for many years means he feels like he needs to be perfect or needs to do everything right, and sometimes he gets really stressed about it. He would need someone who can understand that but also help him relax or loosen up a bit.
A relationship is not the most important thing to him. Of course he cares about you (a lot, actually), but he understands that as demigods, you aren't like other teenagers and you can't just go on casual dates all the time. It's about survival, and especially as head counselor of the Athena cabin, he's super busy with maps and plans and diagrams and all that.
He will, however, make time for you. Whether it's setting aside time after lunch or between lessons, he'll make sure he has time to spend with you here and there.
He has a huge sense of responsibility. He's had to lead the Athena cabin while Annabeth is on adventures with Percy, so he's led them into battle and led command tents in her absence. This taught him all about responsibility.
He's sarcastic as hell. His sense of humor is dry and sarcastic so you have to be able to match that energy!
I can imagine your first kiss was just before the Battle of Manhattan. When you guys got there, you met up briefly and told each other to be careful. Then he kissed you and told you he loved you before you headed back to your respective cabins.
During the battle, he's super protective over you and will keep an eye on you if he can from the command tent. If you're injured he will check on you every chance he gets.
He's worried about you the whole time, regardless of if you're hurt or not.
After the battle he will look around for you frantically. When he finds you he will run to you and pull you into the tightest, most loving hug you've ever received because oh gods, he's so glad you're okay.
Then he'll pull away and clear his throat awkwardly before telling you he's glad you're alright.
Malcolm isn't used to caring quite so much about people. Of course, he cares about his friends and siblings and he would be devastated if anything happened to any of them, but this is a whole new level of caring for him. He's confused because this is all so new, but he finds he doesn't hate it at all.
Cuddling in the Athena cabin while his siblings aren't there! It's such a calm place with all the bookshelves, the wood floors, and the warm lighting. You fall asleep on him almost every time.
You do have to ask him to cuddle. He loves you a whole lot, but he doesn't usually think of physical things first.
Stealing his glasses. If anyone else were to do this he would be pissed, but it's somehow cute when you do it so he lets it slide.
He's not big on affection so it's not often, but that makes it more special when it happens! He does like cuddling, though.
Also hold his hand when he's anxious! It helps him so much.
Sometimes he'll get nightmares (like most demigods) and while he won't sneak out of the cabin to find you or anything dangerous like that, he'll hug you extra tight the next day at breakfast.
He's new to relationships so he may not be the best at being a boyfriend but he does try!
Sometimes he needs reminders to stop working and pay attention to you, and you'll have to tell him if things like going on dates or anniversaries are important to you.
You actually change him quite a bit. Not in a bad way, but being with you has changed the way he sees things a lot! He learns to love unpredictability and spontaneous adventures, and he gets a lot more social. He buries himself in his work a lot less, and over time he gets more comfortable with relationships and physical touch!
He's still your Malcolm, though.
Overall, he's new to this and can be uptight, but he cares for you a lot and is a total sweetheart. 10/10 adorable nerd boyfriend.
