Deception by the Johansen's and the Rosen's in order to help each other stay alive shows the true loyalty people have to one another. The Johansen's deceived soldiers at one point by saying Ellen was one of their children.
Fool me once, shame on you. Fool me twice, shame on me. Shame on you and ONLY you. You took advantage of my giving nature and what you thought were unlimited second chances, and even worse tried to make me feel bad about it. But I won't feel bad.
Narcissism - If you're in a relationship full of ups & downs and you're constantly trying to prove your love and get back what you had in the beginning - look up Narcissism. "everybody deserves second chances, but not for the same mistakes"
Never trust a person who has let you down more than 2 times. Once was a warning, twice was a lesson and 3 times is simply taking advantage. Gotta remember this! Why waste time with a person who isn't a.friend at all?
