Which wrong is right?

One of Kristen’s opponents hit a first serve that resulted in a fault. She then proceeded to hit her second serve without looking up at Kristen’s partner, the receiver. The second serve landed in and barely missed Kristen, who had gone to strategize with her partner. Kristen’s partner did not attempt to return the second serve.

What should happen?

Kristen shouldn’t have gone over to strategize with her partner, so the serve should count, and Kristen’s opponents won the point.

Kristen shouldn’t have gone over to strategize with her partner, so the server should get a first serve.

Kristen’s opponent should have waited until the receiver was ready, so she should serve another second serve.

I’m not sure.
