Frank did not proceed towards the cabin; he turned his head to look at Jimmy, "Call Kodaiski now."
Jimmy took out a burner phone and directly redialed Tom's number, "Tom, Frank wants to talk to you now."
After Tom responded, Jimmy handed the phone to Frank, who walked away to take the call. Jimmy didn't follow, as it was clearly a call to verify his identity.
It seemed like it was just an identity check, but perhaps Tom and Frank talked about something else as well, as the call lasted a few minutes. At last, Frank hung up and walked back.
Frank returned the phone to Jimmy and looked him up and down, then frowned and shook his head, "I really can't tell you are her son, not a bit like her, but alright, let me explain the situation."
As Frank walked back, he continued, "You know I retired from the CIA because I got old and no longer take on missions. I initially settled in Little Rock, then moved to Kansas City, where I met Sara.
