What is the conclusion, falling action, and resolution of That was Then, This is Now?

CONCLUSION
(CLIMAX).  After finding Mark's secret drug
stash, Bryon decides to turn Mark in for selling drugs. He realizes that Mark has been
selling drugs to residents of the hippie house, and that M&M has overdosed on
Mark's drugs.

FALLING ACTION. 
Bryon visits the reformatory in order to see Mark, but Mark tells Bryon that he hates
him. When Bryon mentions the good times they had together, Bryon tells him "that was
then, this is
now."

RESOLUTION.  Mark is
somewhat uncertain of the decisions he has made, replaying the past year in his head. He
wishes for the return of his younger days, when life was simpler and he had all the
answers.
