*Kya and Bumi lost Iroh's badgermole while babysitting the Firekids*
Izumi: Iroh can't sleep without his badgermole, and if Iroh doesn't sleep then Ursa doesn't sleep and if Iroh and Ursa don't sleep-
Bumi: Izumi doesn't sleep
Izumi: no! Bumi doesn't live
Iroh and Ursa: MCDONALDS! MCDONALDS! MCDONALDS!
Izumi: we have food at home
Lin: *pulls into the McDonald's drivethrough*
Iroh and Ursa: YAYYYYYY!
Lin: *orders one black coffee and leaves*
the first months of dating Izumi, Lin would get anxious and alert whenever she heard Ursa cry (who was a baby), so every time after Izumi went to calm down her daughter, she'd come back to Lin and assure her everything is ok
Iroh and Ursa would absolutely kill it at Just Dance
when Iroh and Ursa were kids (13 and 5yo) they'd sometimes try to stay up late at night to receive their mother, when she arrived but normally failed, so Lin would wake them up with breakfast (normally late)
modern Linzumi would take the firekids at some point to meet fluffy cows
Lin used to go, with no hesitation, from RC to the FN just so her children would take their medicine, when they were sick
in a modern AU, when the firekids ask for McDonald's, Izumi would normally say "no" but since Lin is the one who cooks, if she made food already or not (or if she doesn't wanna cook), she'll help the kids to convince Izumi, which constantly ends with her saying "yes"
*Lin and Izumi at the Zoo with the Firekids*
9yo Iroh: ...what are they in for?
Izumi: sweetie, this isn’t prison
Iroh: so they can leave?
Izumi: well... no, but–
Lin, pointing at a meerkat: i bet that one murdered someone
