In the first still, it looks as if Merida is playfully fighting with her father, King Fergus, while her mother, Queen Elinor, is looming in the background - probably wishing she was being courted by a fellow suitor instead of roughing around.
In the second still you can clearly feel the intensity and seriousness of the situation. Merida looks as if she's about to take a stand - perhaps "change her fate".
After viewing these new stills, I went back and watched the latest Brave trailer and if you look closely at 1:34 into trailer - you will see Merida doing what appears to be practicing swinging a sword on her bed.
Though, I'm still curious as to where her bow is - I guess we'll find out on June 22.
