Kaz puts Sam on the couch and tucks him in, then walks back into the kitchen
He leaned on the kitchen counter, grumbling and picking at his nail
Kaz walks over and leans on the counter next to him
Kaz: What's wrong?
"Nothing."
Kaz: ...something's clearly wrong. You can tell me, big brother...
"Nothing. Is. Wrong."
Kaz sighs
Kaz: ...if you have a problem with Sam...then you should just go.
"No."
Kaz: Yes! I-I'm not going to let you bully him...or me...
"Not going to."
