However, Richard was a bit scared that Lara thought he was replacing Ana with Amelia Croft. The older Lara got, the more accepting of Ana she became, being happy that she made Richard happy.

Ana however, still seems a bit sentimental towards Lara and orders the Trinity forces to keep her alive. Throughout the story of Rise of the Tomb Raider, more about Ana is revealed, with an emotional twist at the end.
