please keep in mind that Bertl’s sweatflow is as specific as Reiner’s bullshit. so while ‘normal’ bullshit will mostly just affect Bertl’s face (we call this stage ‘ugh’)
Annie-specific bullshit affects most of Bertl’s upper body (this stage was dubbed ‘ughhhh’ by scientists)
and Christa-specific bullshit usually catapults Bertl’s sweat out of every pore of his body (the infamous stage known as uuUUUUUUUGHHHHHHHHHHHHHHHHHHHHHH)
