6 groups of enemies, all possibly interested on taking a piece of her body.
Alina had no possible way of winning against 6 groups at once, which is why she had prepared some countermeasures in case these 6 had to fight her.
She could have used these countermeasures today, but the sudden move by Xavier allowed Alina to not use these countermeasures.
That should have been the case, but now that the other Travelers were able to free themselves out of the Event Loop too, Alina cannot hide her countermeasures anymore.
Sure, since the other Travelers had not fully freed themselves from the event loop yet, Alina can actually just focus on running away if she wants to save herself.
But she clearly knew that she cannot do that, not with her allies still stuck in this place.
If she leaves, it will be her allies who will take the full force of the enemy Travelers. Alina had no heart to just let that happen, even if she's wary of her opponents.
