After taking care of the big problem all on her own without getting rid of the restriction, Elena was in a very good mood. What she was doing was actually extremely dangerous. Obviously she would not have died if something went wrong but if Elena had taken even a single wrong step during the whole fight, she would need to break her restrictions.
So this whole battle was a very good practice for Elena. This avatar was also most probably one of the strongest opponents she could find in the mortal world, so this was a very exciting battle for her. Elena was also happy to know that her combat instincts were still in working order.
This whole spectacle was not witnessed by anyone as before engaging the avatar, Elena had told all the people she had rescued to go far away from their location. As the battle also took quite some time, Elena was sure that they had already reached a safe location.
