Out of all the Hayes siblings, Ollie was probably the most laid back of the bunch. Alex was bound tighter than a bloody button, half the time, and Ros could be a bit of a, well, woman about some things. Oliver, though, well he was the most soft-hearted. Loyal to a fault, he cared deeply for his friends and family. He was the one that took care of his siblings. Bandaging Alex's scuffed knee's and carrying Roslyn around on his shoulders while he saved her from the mad dragon. It stood to reason, then, that despite the fact he was the softest of the three and in possession of the most genial demeanor he was protective to a startling degree. He'd always been in possession of large swaths of daring, nerve, and chivalry. He'd be embarrassed about being so Gryffindor if he hadn't been so proud of it. That just meant that he just wandered into situations head first (Roslyn had gotten that particular habit from him, unfortunately. Headstrong, that one, not that he'd regret it much) and was completely unapologetic about it.
He had zero hesitation about hovering over his sister and her pretty friends, thank you. It wasn't even that he thought women couldn't handle themselves, either. He'd seen enough women elbow deep in the remains of dark creature innards (his sister included) and at the wrong end of a pissed witch to know that. It was always the delicate looking ones that had a mean hex rearing to go. It just made him feel better if he knew there was someone watching out for them is all. Aiden, he knew, felt the same though his cousin would never admit it. St. Patrick's could get a bit out of hand and he wanted the girls to have fun without having to worry about some bloke trying to get fresh. They deserved to just be and so he was fine with being the one to blend in the background and watch, poised to discourage any interested parties if they got too close. Not to say he was going to be a complete sad sod, either.
Maisie and Jade were quite pretty and it was St. Paddys. With an amused eye he watched as Ros won her friend a stuffed unicorn, grinning into his beer, and repressing a chuckle. Of course she would, he thought fondly, as he walked up to them both. "Did you have time to miss me?" he quipped, grinning so wide his teal eyes, the exact same shade as his sisters, crinkled around the corners. "Unless you mean Alex, in which case, you've got the wrong Hayes brother, love. He's way less fun than I am, anyway. Though I suppose he's just as pretty." and a lot more blatant about scowling at men who looked Ros' way. And because he wasn't a complete hypocrite he made sure to keep his own eyes from straying too far down Maisie's face despite the fact that he took notice of how nice blue looked on her.
Ollie was a Gryffindor in throes of wanderlust, which was a hazardous pastime. He loved his job as much as he'd loved any woman and that left little time to no time to focus on the lack. (Right then so Ros took after him a fair bit. He already got enough grief from his caterwauling mother for it. He didn't need additional judgement for his sentiments on love to be bleeding into Roslyn's psyche.) Most women liked to pretend at being strong enough to date him (they were not) but the truth was that the late hours, the traveling, and the near constant visits to Mungo's got a bit much. He wasn't ready for a desk yet, despite his mothers thoughts on the matter and so he was stuck at this impasse of meeting women who were interested and interesting but things just didn't work out. He'd thought, with Adrianne, but well. Even a strong woman like her hadn't been able to handle it, in the end. Now wasn't the time to focus on all that, though, as he took a step forward and gathered his sister in arms. "Merlin. Why couldn't you have been someone with an attachment to shawls?" he said, long-sufferingly. "You look quite nice" he added, tugging at her bun, and knowing after years of education on women to know you complimented them when they wore nice things despite your personal feelings about parka's in the height of summer. It was a great idea, really. The first time he'd seen her in a pair of shorts when she was sixteen and not scrawny anymore he'd just about had an aneurism.
He'd definitely overreacted in retrospect. She'd yelled about men being prigs and hadn't talked to him for a solid week before he'd apologized. It still bothered him, but in the sense that he didn't like men that stared at his sister like she was a slab of meat on the table. (Or his mother. Or the person he was with. Anyone, really. It genuinely bothered him.)
"Three." she agreed, smothering a grin. "He's the best." she admitted, with a great deal of fondness. "He's told me a bunch of times how proud he is about me being so good with a wand but he still worries and hovers like a bat." she long ago realized it was just how he was. Ollie was the kind of bloke who helped old crones cross the street or helped unload a neighbors groceries. What was impressive was that he was genuine about it. It was hard to stay mad at someone like that for very long in the face of that sort of earnest thoughtfulness. She privately thought most of the women he'd dated weren't worthy enough of her idiot of a brother. Alex, at least, knew his worth and so she worried about him less. Aiden she didn't even bother with. That boy was so not in a state to settle down. She hoped Jade would fair well with his ridiculousness.
"I'm glad!" she said, pleased she'd made her friend happy and amused by their continued silliness. She laughed as Maisie curtsied, snorting a little, as she nabbed one of the drinks in her friends hand. "Probably out scowling at some poor so- bloody hell! You realize your arm weighs a ton, you bloody giant." she scolded, digging her elbows into Oliver's ribs as he responded with an amused chuff. He could at least have the decency to pretend it hurt.
