The thing was, she could never come back even if she wanted to.
Because she was dead.
Lilacstar had never been a popular leader by any means, but when she decided to punish rebellion by drowning a group of four apprentices, half her followers decided that they had had enough. Together, they were able to split off and eventually form their own clan.
Some were too afraid to leave.
There was uneasy tension between the two clans for a while before it eventually snapped again. Several heated battles later, an outraged Lilacstar called for a small group of cats to start slowly picking off the other side one by one, without the clan's knowledge. Incidentally, this group consisted of the she-cat and the tom mentioned in previous chapters; and, true to their word, they proceeded to silently 'take care' of their unsuspecting victims particularly well.
In the end, the she-cat was finally found out and killed.
The souls of those she'd murdered, it turned out, were there for her judgement before the ranks of StarClan.
She'd indeed been knocked off the board, and there was no going back now.
