What does Thomas ask Judith in the car after the row?

When Thomas allows Judith in the car (why for heaven's sake) after the row at the party, he asks her two questions.
First 'Warum gerade er'?
Then there's a second question. It took me some time to properly hear what he said. For all those who had the same problem: "Was hab ich dir denn getan?".

After her silent answer he still doesn't trow her out of the car ...
