obviously Tayuya still has to go level 2 curse....because all other did that... but one thing i can think of that shika can try is....get hold of Tayuya with his shadow bind....and we know during shadow bind the target reacts the same way as the user.....hmm so...he can make tayuya throw the flute to himself or make tayuya break it...hmmm well we are not sure if tayuya has a spare flute....but its higly unlikely that she would...since she won't be expecting it....once he does that Tayuya won't be able to control the summons...so that would take care of the level 1 curse.....ofcourse after that Tayuya will go level 2....than we don't know whats gonna happen.....or what sort of form she'll take.
