Loki arrived with Darcy on his arm, dressed in a well tailored black suit. He too brought a gift of a bottle of fine wine, which he tucked into the crook of his arm as he knocked upon the door.
If anything, he didn't expect a network party to not have copious amounts of alcohol involved, considering the last festivity ended up with their apartment set on fire and an eviction notice. Sadly, Loki hadn't brought a bottle of that which Stark dubbed 'rocket fuel' made for Asgardians. That was safely tucked away where Loki kept his things, and no one else ran the risk of instant liver failure if consumed, undiluted.
He waited patiently with Darcy for the door to be opened.
