Jack was trying to get her life back on order. With Max gone, there was this empty vacuum, that she really had no experience on how to fill. Max had filled the gap of Albus, Albus had filled the gap of Nemo, Nemo the gap of Chase, Chase of Vito, Vito of Elliot. Jack had not realized this was her nature - that while she was not one for a group of friends, for a variety of acquaintances, she always had a person, a person to pour into, a person to protect and serve, a person her heart could dedicate itself to.
And Max was gone.
She poured her time, of course, into the two kids that had become her life. Extended from that was Sunny's close friends, Lize and Tomas, as well as Viv and Keith, who had taken up residencies in her home. Then there was returning to work and throwing herself, 100%, into that work, as well as back into Quidditch. She did that, until a pesky window of time opened up in her schedule.
That was when she decided she had better contact Nick Potter.
She sent him an owl and when the time came, dawned a jacket and slipped out of the insanity that was her home. Within moments, she was walking up the steps to Number 12 and slipping inside, sneaking across the hallway and into the kitchen, where she would await Nick.
