I saw in my german textbook a sentence
"Und wer den neuen Tatort am Sonntag nicht gesehen hat, findet ihn danach noch sieben Tage lang im internet: in der ARD-Mediathek."
My question is: what does the "ihn" in the above sentence refer to? Does it refer to "den neuen Tatort"? Or does it refer to the "wer" just like the "ich" in "wenn ich Zeit habe, sehe ich Filme"?
Another question is: past tense is used in the first part of the sentence (hat gesehen), then shouldn't past tense be used in the second part of the sentence as well? So it should be "hat gefunden" instead of "findet"?
