Rebecca is a bit of a daddys girl.
There are certain things that they dont align on.
But I think at the end of the day she really loves her father for who he is.
Hes quite protective of her.
Hes not afraid of whatever company hes in.
Hes very respectful, but hes going to have some obstacles.
And they may have his own making.
Mathesons recent credits includeThe Affair,The Good Fight, andHart of Dixie.
