"What brings you here?"
"I came for a talking with you."
"What brought you here?"
"I come for a talking with you."
Both sentences are right? Please.
But, can I use "come" ,not "came"? Please.
You have arrived, so it is I came to or I have come to.
One more question: can I use "brought" in this case?
That is : "what brought you here?"
