Answer: Oklahoma or Texas
Explanation:
In the United States, when there is an accident involving multiple people who are residents of different states, lawsuits arising from the accident can be heard in the state where the accident occurred, or the state where one of the defendants is a resident of.
In this case the accident occurred in Oklahoma so it can be heard there.
One of the defendants, Blake, is from Texas so the case can be heard there as well.
