The character of troubled teen Samantha Walker aka Sam played by Ashley Rickards appears in Season 6 (21 episodes) of ONE TREE HILL (2003) from (1st September 2008 - 11th May 2009).
The last episode she is credited only and does not actually appear.) She does not appear in the first five episodes of OTH; so therefore, it does not look hopeful for Season 7. Hope this helps.
