Appears that Kim's response was something like: "We? This is your mess, not mine." Or, "Turn yourself in." Or, "I can't help you. Never call me again."
Whatever she said, it sets Jimmy off.
It wouldn't make any sense for Jimmy to ask what they would do ... UNLESS ... Kim actually did have some involvement in the Breaking Bad story. The last we saw of Kim before the time jump, she was packing her things, so we don't know for sure that she didn't have some involvement.
