When Thor, Loki and a handful of Asgardians sought refuge on Earth, Tony took back Stark Tower and turned a majority of the offices into apartments for Earth’s newest refugees. Everyone had been welcomed with opened arms and kind words, but the moment someone noticed Loki was back… all hell broke loose.
For weeks Thor and Bruce tried to vouch for the God of Lies and his reformed ways. So as the cousin to Pepper Potts- she was the only family member kind enough to take you in after hitting a rough patch in life- you stayed on the sidelines and watched everything unfold. No one trusted Loki, not that you blamed them, but you felt a bit bad about your fast judgement after hearing Thor explain that Loki’s mind had been messed with just as Hawkeye and Doctor Selvig’s had been.
The God of Mischief was excellent at feigning ignorance to all the hostile environments he walked into, but he couldn’t keep it up forever. So the first time you saw his mask crack and his shoulders slump when he suspected no one was paying him any attention, you got fed up with everyone’s attitude and decided to throw caution to the wind.
