I used to think about James and Lily going absolutely mad shut up in Godric’s Hollow, but as I’m writing this long fic, it’s occurred to me that these two would never sit idly and let themselves rot for two years.
They kept busy.
After the shock of being pregnant and of their lives as they know it being turned upside down wore off, they sit down and brainstorm ways they can still help the Order. They invite Dumbledore over for tea and they more or less ambush him, insisting that though they can’t use their wands in battle they can still be of use to the Order, presenting their list of possibilities.
Lily becomes the Order’s potion mistress: their kitchen becomes hijacked with potions supplies, four or five cauldrons simmering at any given time, people stopping by to pick up and drop off various orders, a long ledger of supplies spell-o-taped to the wall, figuring out the Order’s long and short term needs based on various missions, working very closely with their resident healer-the one who will deliver Harry, actually, because they can’t go to Mungo’s for half their injuries-and deciding what’s available and what their healing needs are, Dumbledore asking Lily if she could invent this or that potion, Lily rifling through her old potions books and asking Dumbledore to find this specific books, Lily going out under the cloak to track down a specific type of weed that only grows in one place. James cringing because there are animal parts in the ice box, again, but he shoves them aside and grabs another butterbeer. Lily gagging at smells that never bothered her before; plodding on anyway because at least she’s doing something.
James becoming the logistics manager/strategic manager for missions: their kitchen table barely visible under layers of maps, keeping mental track of where all the Order members are at any given time, working out patrol and surveillance schedules for various members, knowing what everyone’s code words are for their various missions, listing out parchment’s with everyone’s strengths and weaknesses and figuring how best to utilize those strengths. Vanishing ring after ring of coffee stain mugs on them because he spends all-night planning sessions with Moody and Dumbledore.
Opening their home, even in hiding, to the Order’s needs. Offering their spare room, at least until Harry comes, and their couch after he’s born, as a safe haven for people to rest in between missions, always having a casserole in the fridge for someone who may stop by for a quick meal in between missions, serving as a safe place for injured members to recuperate.
