Joseph saw his brothers and recognized them

"When Joseph saw his brothers, he recognized them"

he disguised himself to them

"he acted like he was not their brother" or "he did not let them know that he was their brother"

"Where have you come from?"

This was not a rhetorical question even though Joseph knew the answer. It was part of his choice to keep his identity from his brothers.
