Liam sat quiet as a mouse on top of the stairs, chin in hand, watching drowsily downstairs where he could see a sliver of the kitchen where his fathers sat, oblivious of being observed, Jack bracketing Will's lap, his face buried into Will's neck, lips just ghosting against the skin, in Will's embrace.
Liam couldn't make out the words crooned, but it was, in Liam's opinion, the best part of the evening seeing his parents like this; caring and loving, most likely talking about the past day's escapades, if the silent joint laughter was any indication. The kisses spoke more loudly and made Liam blush, cueing his bedtime.
Certainly, he'd been tucked in before, but it didn't take much to stealthily stalk to his vantage point.
With his feet shuffling drowsily, Liam headed to his room, assured once more with a child's conviction, that all was right in the world.
