Not a secret wife, possibly an ex-wife.
Married at 19, pretty young, divorced shortly thereafter.
Maybe didn't tell her, bad, but not trashy and not uncommon for very young enlisted to move on.
If anything, Dakota should exercise better judgment.
Dakota is a man, an honorable man.
Sadly other than giving birth to her baby conceived with a moron, I give her sense of judgment a zero. Where is her college or vocational education? Where is her job and career search, her independence?
Seems like one of those young people whose parents have to pick them up and carry them (and their children) all of their lives.
