Since chapter 38 I've come to this prediction that this will happen.Amu and Ikuto will both be confused of their new found powers but they won't fight evil stepdad (yet),than Amu and Ikuto will go back to their original selves and, Amu will go to Ikuto saying she is sorry atau somthing about the way she treated him and stuff then Tadase will
go to ikuto and might say he is glad that Ikuto is alright.thats when evil stepdad will decide to
make his exit(like the b**** he is) telling Ikuto its not over atau somthing.I don't think Ikuto wil go back to his house he might stay at Tadase's house and Amu may visit him.This is only my prediction but who knows what if some of this stuff comes true(shrugs shoulders) I say anda never know. ^^ komen ME PLEASE ^^
