Yes. Heck I starting seeing that everywhere ... even in my sleep!
Somehow I did not fully understand this either. I remember her making a comment about staying on Earth, but I had not fully understood that she had actually been left behind, somehow. Makes me feel better someone else missed it, too (not Shard, but hulugu).
Too bad she stayed behind, Dee popped herself, Gaeta wasn't patient enough, etc.
That actually makes me feel sad for those characters
