[OOC: This follows immediately from
this prompt and
the RP with Sharon.]
Sam didn't want to ask Tony Stark for help, but unfortunately, Sharon was going to need the assistance of the current SHIELD head and his resources. It wasn't something Fury would be able to take care of, and Steve, alas, would be able to do very little for Sharon that Sam couldn't himself.
(Which was almost nothing.)
So Tony Stark it was. Sam was impatient enough go bang on the window of Stark industries and demand to talk to him, but it occurred to him in time that it would be pointless to do so when Stark might not even be in. So he sent an email instead, to the most secure address he had:
Subject: URGENT
Need to speak to you. SHIELD business. Let me know when.
