Stellerite knew that even with her limited field practice in combat she should have been doing better. This was why she was the bait in traps instead of the ambush. Because she had absolutely no control over the situation, her outward presentation was starting to slip and crack.
The katar was easily handled, dismissed back to subspace where it would rest because this was clearly a losing battle unless she wanted to expend the last of her energy on a last ditch teleport and put her hand into the page's chest and...
That didn't sound fruitful in the end.
When the lid hit her arms, which she'd raised to protect her face, she decided she was done and immediately just disappeared, choosing to teleport out rather than deal with anymore trash thrown her way.
