Jay and Brian are the biggest Lees of the group, the difference is how they behave. Jay is a little shit who starts chaos and "fight" just to get wrecked. While Brian is a little bit nicer about it - he'll simply walk to the nearest person and ask for tickles.
Tim is the biggest ler of the group. If there is anything tickle related is going on, Tim is joining in it.
When tickling anyone shy, Jessica loves calling them out and pointing things out dead on. If someone's in either a Lee or ler moods, she'll clock it and call it out immediately.
Sometimes, she'll wait until she is with the rest of the group, than go "hey guys! Brian is in a Lee mood, let's wreck him!" to give the Lee the attention they deserve.
Alex can't handle anticipation and verbal teasing in any way. More embarrassingly, if he is teased long enough, he'll get phantom tickles strong enough to make him giggle.
Jessica wheezes and snorts a lot and has an airy laugh in general.
Alex definitely tickled someone on the Marble Hornets set for "not paying attention to the script" once.
Brian definitely squeaks and kicks a lot.
Alex is a chaotic switch who loves starting shit. He'll start tickle fights, challenges and games just to entertain himself and rope everyone in.
Jay sometimes edits scenes from the Marble Hornets set to look like they are tickle scenes or at least implied to be tickle scenes, than set it to the boys from burner numbers. Seeing them all flustered and blushing the next day is worth it all.
Alex is not a fan of facial/mouth tickles. Most he can tolerate is tickly kisses from Amy, but even the idea of a raspberry makes him want to fly out of his skin.
Brian is a speedy ler and doesn't let anyone get used to the sensations. He skitters and spiders and swipes his fingers everywhere and jumps from spot to spot.
Before getting tickled, Alex needs to take off his glasses and put them somewhere safe. Because he is myopic, he requires glasses 7/24 and he doesnt want them to fall off and get cracked.
If something tickly is going, they are in a house and surprisingly Jay is not in a Lee mood, than he'll dip out to find a feather or a feather duster.
Alex smirks and grins a lot before he tickles someone, or when he is in a Ler mood in general.
