Dick Grayson

[it starts much the same as it did with Matt -- Dick enters Stark Tower in civilian clothes, under the guise of business. in one of his better suits, he carries a briefcase with the Nightwing suit in it, something Lucius cooked up for Bruce ages ago making sure his kit doesn't ping on the X-Ray machine where carbon fiber and Kevlar don't show up on the metal detector to begin with. he doesn't bother with his badge, even though it's in his wallet. he's not here as Dick Grayson, Bludhaven police, he's here as Dick Grayson kind of-sort of heir to Wayne Enterprises]

[(Lucius has been generous or cruel enough to let him have Bruce's seat on the Board of Directors, in recent months)]

[not that it particularly matters for long, however, as once he's through security, he heads for the reception desk to ask after the bathroom. then he's here as Nightwing, ready to climb the elevator shaft up to the penthouse like the right of passage he's heard it is for street level Capes]

[leaving his clothing hidden, he sneaks into the elevator through a maintenance shaft. he takes a moment then, looking up the shaft as he stretches, the elevator somewhere high above him, lost in to the dark and the distance even with the lenses in the mask, and after a beat, he starts:] Hey, computer guy? I'm Nightwing, I'm a friend of Hawkeye's, from Gotham, and I'd really appreciate it if you didn't drop the elevator on me while I'm doing this.

[apparently, he at least knows JARVIS exists, even if he doesn't remember his name. either that or he's just assuming, based on some of the defenses Bruce had on the Batcave. either way, though]
