If Rosa could've teleported herself to the location given in order to get her weapons faster, she would've. Of course, no such abilities have been given to her (not yet, anyway), so she has to do it the old-fashioned way: walking. Walking quickly. She doesn't quite break out into a Holt Power Walk (the most energy-efficient method of movement, according to him), but it's close enough. If she didn't think it'd look desperate as fuck, she'd run.

She gets to the forge soon enough, and before long, she's practically barging her way in. She hasn't set foot in the place before now, and as she opens her mouth to say something (likely demand her weapon(s) from Leonardo), she stops herself to do a quick scan of the place. It's what she'd expect, given its title of "forge." Nothing overtly interests her, so she's hastily making her way towards the Father of Invention.

"Leo! Hey! I got your message. What d'you got?"
