You know how she essentially absorbed Tallis's soul after she killed her? Well, when she tapped into her power during the fight with Homucifer, something went wrong. She used too much and woke Tallis up.
Tallis's soul is fighting for control of the body and is turning Julie into Tallis. Physically, at least.
More funfacts that no one cares about.
Those stunguns that Imuka gave Hal and Shinji were brought into WAOAA in 2012, and only used once since there introduction, on acount of Imuka never being involved in plot.... and all the speessmarines being too MANLY to use any thing but a real gun.

The damned queen and the relentless knight.

If she had broke it down that would be one thing, but she just kinda unlocked it....
and sorry.
