She works on her own. And is immune to status effects and being put in a jar, as she is not organic. XD

X-I2 breaks out of the jar and possesses Tia! "Inssssssolent little..."
Tia/X-I2 knocks out Xion with a heavy book, then takes the frozen Malta/X-I and gives her a Remedy. "Thanks," she says. "Now to start HAXORING! YAYAY!!"
"What ssssshould I do with thisssss one?"
"Loxor him in a closet or something, foo."
"Asssssssss you wissssssssh." Tia/X-I2 takes Xion and locks him in his closet, then barricades it with random large and heavy things.
"Now then," Malta/X-I begins, "To haxor!"
She hacks into the security network and activates all of the defensive systems, locking all of the doors leading in and out of the building so no one can exit or enter. Malta/X-I hacks into the intercom and says in Malta's voice, "Attention everyone! There has been a security breach. Everyone is to report to the Mess Hall (do you have a mess hall?) for a security check immediately. No exceptions!"
