Leigh knows, he knows about them.

The secret is uncovered completely by accident. Leigh never pried nor so much as suspected that there was anything less than platonic going on between them, he simply stumbles across it, a bystander to their romance.

They're not exactly subtle about it. Castiel gripping Lysander by the collar, perched above him and giving him such an intense look. It doesn't leave the matter open to interpretation. Even if Leigh had his doubts about the scene, he wouldn't have stuck around for clarification.

His presence unnoticed, he backs away towards the front door, hoping that they'll show his couch some mercy and relocate their passion to Lysander's bedroom. Not wanting to intrude, he heads to the shop's storeroom. Sewing always did give him a chance to think.

He decides immediately that he's not telling Rosalya. He shouldn't keep secrets from his girlfriend, he can imagine her pouting at him, sensing from his outward air that he's hiding something; Rosa's always been good at picking up on that sort of thing. She'll persist and try to get him to come clean, but it's not his secret to share.

He doesn't plan on saying anything to Lysander either, Lord knows he'll fall flat on his face at any attempt to drop it into conversation. Lys will bring it up when he's ready and Leigh will have to wait patiently for that moment to arrive. But still, he'd like for Lysander to know he's loved and accepted wholly without any hesitation.

He waits for an unsociable hour, when Castiel is certain to have left the house or at least finished what they began, before journeying home. When he reaches the door to the apartment he pauses and listens to the soft hum of the television and the repeated sounds of feet stepping along the wooden floor before unlocking it. Even with that, he jangles his keys harshly to make his presence known.

"You're home late, did you have a busy day?" Lysander asks, looking up at him from the couch. Castiel is beside him, wearing a jacket indoors, which mostly covers the fresh marks on his neck, but not all. Leigh tries not to stare.

"I had some work I needed to finish," Leigh begins, venturing into the open plan kitchen, "Have you eaten?"

"There's dinner in the microwave if you're hungry."

He wolfs it down, having delayed his meal by three hours or so in his unplanned detour. While he eats, he looks over to where Lysander and Castiel are sitting, shut off in a world built for two. He notices it now, how Castiel's cocky, eternally amused grin seems permanently fixed to his face when he looks at Lysander, how Lysander seems less lost in thought and more lost in someone else. Leigh sees it in hindsight, those looks that lingered now seem to have meant something.

Leigh smiles lightly to himself, deciding that whenever Lysander decides to tell him, he'll welcome Castiel into the family with open arms. But even more than that he's determined to make sure Lysander feels loved and valued no matter what.

A few days later, on a lazy Sunday where both brothers are sitting on the couch and ready to watch a film on Netflix, Leigh browses through the 'Gay and Lesbian' section, earning a curious eye from Lysander. He chooses an old comedy with a gay couple playing the leads, it's a classic Leigh explains, saying nothing more. The film earns a stream of laughs from the pair of them, but Leigh's intentions had less to do with comedy and more about solidifying the idea in Lysander's mind that Leigh is someone he can trust to be a constant ally.

The next time Leigh visits his doctor, he grabs a leaflet about local LGBT groups and helplines . He places it amongst the junk mail the following morning, allowing for the assumption that it came through the door. While he's unsure if Lysander needs them, he wants him to have somewhere to turn to if he isn't ready to talk to him.

Lysander still hasn't said anything yet, but he gets the feeling that when he does, his brother will meet the news with nothing but warmth and respect.
