yh i think he will unless ichigo get a way 2 control him did u read the manga did u c ichigo when he lost control what happend against Ulquiorra ichigo or the complete hollow form used cero n used sinedo (thats like shunpo but 4 hollows) ohh shunpo is foot steps the skill shinigami use to kinda teleport for a short space ....
Ulquiorra knowed its sonido cuze sonido user can teleport throught objects but shunpo user cant ...
n after Ulquiorra thought that he killed the complete hallow he was sprized that ichigo is ok in that moment he knew that it wasn't ichigo fighting it was the hallow with in him cuze hallows can use fast regeneration.
when ichigo was takenover by the hallow he almost killed Ishida
if ichigo lost control again he will or the hallow with in him also known as (Shirosaki Hichigo) will really kill every living thing around him
will thats just my opinion
btw cool topic
