Lev. Abby's face. The thing that stops Ellie's hand. The point of love, the game suggests, is exactly this — not the happiness it provides but the anchor it creates, the specific person who makes the choice visible as a choice rather than an inevitability. Ellie sees Lev and sees what she had and gave away, and the love that gave her more to lose is also the love that makes her capable of the thing she is about to do.

The question is not rhetorical. The game is asking it genuinely and answering it with the action rather than the words. The point of love is that it keeps being the point even when it has only cost you things. It is the specific form of meaning that does not require being painless to be real.
