Well, now she knows.
With Hydras commands inside his head, Talbot infiltrates Robins room and examines her drawings.
When Robin cant explain the drawings, Talbot knocks out her mother and kidnaps the girl.

Robin reacts in characteristic fashion when Talbot informs her of his kidnapping intentions: I know.
Luckily, Coulson and Mack soon notice a glitch in the video feeds for Robins room.
Using his knowledge of Hydra commands, Coulson gets Talbot to surrender, freeing Robin.
Meanwhile, Daisy and May have stormed the Hydra base.
When they found Hale, the Hydra general made the uncharacteristic move of surrendering.
She then throws Fitz and Simmons against a wall and is only reigned in by her mother.
Ruby tells Daisy that she was her hero, but its too late for all that.
A shaken Yo-Yo comes in and immediately recognizes Ruby as the person who cut her arms off.
On top of that, Yo-Yo sees Rubys newfound powers going haywire, and puts two and two together.
As might be expected, Hale is not too happy about all of this.
She contacts the alien Confederacy and tells them to kill S.H.I.E.L.D.
if they want their Gravitonium.
