Headcanon P.E.A.D Timeline Of Infection

Moxxie attends a weapons expo in gluttony as part of a multi-day business trip
only after he begged Blitzo for months to be able to go
during the expo, he stops off for Lunch at a fast food diner
a demon with p.e.a.d, walking past Moxxie and eating food, accidently drops a few of their chips on Moxxie's plate while he is distracted looking at firearm paraphernalia
Moxxie is now infected

Moxxie returns to Pride a few days later, already experiencing the 1st stage of p.e.a.d, he discounts this as him eating too much food in Gluttony.
Millie prepares a large meal a few days later as a surprise
the pair, while enjoying the meal (with Moxxie enjoying it a little bit more than usual), share a plate of pasta, eating the food while kissing
Millie is now infected

Blitzo was hiding in the roof observing this
after being satisfied he's watched enough, he attempts to sneak out of the apartment
on the way out, he grabs some of the leftover pasta
Blitzo is now infected

2 weeks pass and the trio become aware of their p.e.a.d infection after they reach stage 2 and start gaining heavy weight
blitzo claims he just ate some leftovers in the fridge instead of admitting he snuck into their apartment
3 weeks later, while in the middle of the 2nd stage of p.e.a.d, Loona, who finds the situation with Moxxie hilarious, makes a mistake
she absentmindedly steals some of Moxxie's food from the fridge, and eats it, in front of him
Moxxie tries to warn her, but Loona dismisses the concerns as "she'll be right mate"
Loona is now infected

a month or so passes, Moxxie, Millie and Blitzo are in to stage 4, and have started to settle into their 'heavy' weight
Loona is in the middle of stage 3, and has not taken it as well as the others

Stolas has observed Blitzo for the last few months, and helped him come to terms with the disease
he continues to love Blitzo for who he is, and he quickly comes to not only accept, but enjoy, Blitzo's new body
having done exhaustive research on p.e.a.d, Stolas has slowly come to the conclusion that he wants to be infected
every day he visits Blitzo and tries to tempt himself to infect himself, but he gives up at the last second every time
eventually, while watching Blitzo eat a plate of chips, he notices one of the chips falls out of his mouth, covered in saliva
after hearing a groan of pleasure from Blitzo's mouth and the gurgle of his gut, he eats the chip in front of Blitzo
Stolas is now infected

some time during this, Striker infiltrates M&M's home in an attempt to learn more information about Blitz
he is captured by M&M while Striker is distracted by the combination of the amount of food in the apartment and witnessing M&M "making love"
the pair decide they want revenge on Striker for all he has done to them and their friends, they go back and fourth, but eventually they decide on a unique form of revenge
Striker is now infected

Loona is well into stage 4 at this point
she has relied on Octavia as a pillar of support as she struggles through p.e.a.d, which Octavia has been more than happy to provide to a close friend
Octavia has struggled to reconcile her father's desires with contracting p.e.a.d and comparing it to the distress it has caused Loona
while Loona is enjoying another one of her large take away meals, Octavia, due to a combination of being in deep thought, thirsty, and being a dumb teenager, takes a big sip from Loona's drink
Octavia is now infected
