It was more than that. We can escape a great deal of things. It was the only option available to us if we hoped to live, but we could have accepted our death. We didn't. [Death is not something that Lexa fears so much as pain being caused for her people. She hoped to go along for survival, to ensure that she could return later. Survival is something she understands, but she also knows that it might have been her time.

Of course, that she took the path of escape, that she saw it as a way out, means she accepts that it just isn't her time.

Still:] Death is an escape just as much as living here is an escape. You valued your life enough to keep going. That's why you're here.

[Underlying this belief is the fact that someone recently reminded Lexa of the value of her life. Drawing upon the heart of that wisdom makes Lexa miss Clarke painfully; that pain resonates, but there's some happiness that she can draw upon, too. She knew Clarke long enough to deliver these words, and hopefully, by coming here, she secured her survival.]
