Soldier: "nobody is going to steal my cupcake!"
Pyro: *sets everything on fire*
Demo: "you've gotta look after the kids we'll have lass, you'll be a great wife :) ."
Heavy: "heavy needs you. It is lonely just with sasha."
Engineer: "are you sure about going outside by yourself? Don't sweat sweet pea, Dell's comin."
Medic: "nononnono, where are you going? You're sick! Just stay with me for little longer. Don't make me restrain you."
Sniper: "you gotta know how to survive in this world, lucky im here aintcha?"
Spy: "you're too pure for this world, people will try to take advantage of that. Stay with me, its safer.."
