Shinji gets whacked on the back with a “thump.”
There is also, in their actions, a sense of the other two beating up on the thick-headed Shinji.
The shot continues until Shinji reacts, lifting up his head.
Shinji does not understand.
DUO:“- TO US!!”
SE <<Thump!>>
SHINJI:“Uwaa!”
Kendrix: Let's just appreciate the expressions here.
