He didn't expect anyone to come looking.
(Or: Wylan Van Eck is found, and then - slowly, imperfectly, one real thing at a time - he learns what it means to stay.)

Summary
After a year of staying sober, March has a relapse. Things quickly spiral out of control.
In the end, it was just another thing to talk about when people asked. Now that—well, that was worth the risk. The way their eyes widened, clear with care and concern. How their voices were always hushed and cautious. Then if he was lucky, a hug. Someone who’d coddle him a little. Someone who’d listen with understanding. Yeah, that made it all worth it. He missed that gentle kind of affection. He missed getting it from his wife.

Summary
Holland pulls the freshly lit cigarette out of his mouth. “What’s your fucking deal, Healy? Seriously?”
“My deal is that you sent your daughter to a sleepover on the night of your wife’s death anniversary, and that it freaked her out enough that she called me and begged me to make sure you were alright.”

Summary
"Mr. Grace," Holland hisses.
Grace honest-to-God flinches, mouthing "Mister?" with great confusion.
Their eyes meet, and Grace's mouth drops open. He yelps. "Mr. March? What are you doing here?" he asks, voice hushed. "How did you get here?" He sounds amazed. Why is he amazed? Does Grace think of him as a shitty detective? Why is he so amazed that Holland found him?
Holland is rather offended.
or: ryland grace is holly march's teacher. when he disappears one day, holly enlists the nice guys agency to find him.

like fathers, like daughter by flufferss

Summary
Grace roughly knows that March is a widower, because Holly confided in him once—albeit vaguely—but he managed to extract a brief summary of what happened. A tragic accident, a fire that burned down the March family's home, a mother who passed away, and a father who wallowed in guilt and grief. Grace has never known Mrs. March, because she’d passed away before Holly became his student. The seat next to Mr. March during Parent-Teacher Conferences was always empty.
Now it's occupied by a Mr. Healy.
His brain clicks. Oh. Grace briefly entertains the idea of congratulating the new (?) couple.
or: holly march is one of mr. ryland grace's students. parent-teacher conferences with holland march are just awful—until a jackson healy appears.

Summary
In all the chaos of the "Amelia thing," as Holly calls it, or "the weirdest goddamn week of my life," as March calls it, or "the case" as Healy calls it, the bandages on March's wrist didn't exactly slip Healy's mind, but they weren't at the front of it. Now, face to face with the scar, the question of those bandages is suddenly all he's thinking about.
Or: March gets his cast off. Healy wonders.
