Ellie was too busy quaking in her boots at the conflict, trying to figure out what the hell was going on, to notice the smile on Yua's face. Her fight/flight instincts were screaming at her and she just wanted away from that place right that moment and it was taking every bit of willpower she had to stay there with her, at least she hoped, new friend. She warily watches the boys head up towards the school and releases a relieved sigh, still rather tense, but glad that the conflict had now passed. She wasn't really paying attention to what was going on around her, and actually released a slight yelp of surprise as she felt herself suddenly off balance, reflexively letting go of Yua's arm as she tries to regain her balance.

Once she's steady on her feet she looks around, slightly baffled. What just happened? It took a moment for her to notice Yua on the ground, and she gasps worriedly, -Oh gods, she tripped and I just let her fall, I should have tried to catch her. What is wrong with me? what kind of friend would just let go and let her fall?- she mentally berated herself as she scurried around the Luggage and took Yua's hand, trying to pull her to her feet, "I'm sorry I'm sorry I didn' mean to let go!" she apologizes worriedly as she scurries around to try to pick up the luggage that Yua probably knocked over when she tripped over it
