Why yes he did have all the leverage. And he intended to use it, no matter how much it pained him. Ronan was going to have to swallow his pills, literally, no matter how bitter they were. This time it wasn't debatable.
Grasp didn't flinch when Ronan shouted suddenly, but he listened. He watched patiently as Ronan shifted and maneuvered. "Don't ya think I know that?" He interjected, eyebrows furrowed with a bit of disbelief, but mostly frustration at the situation. "I know ye're a completely different person when ye're on those things. I don't like it any more than you do. I miss my brother when you take them. It's why I'd half-baked made myself believe ya were doin' fine without 'em..." He'd known; deep down. He'd known Ronan was off his meds. But he'd been happy... giddy even. Joyous and devilish and with a sparkle in his eyes.
Kiernan felt deflated, despite himself, when Ronan agreed. "Okay," Grasp interjected, before Mars mentioned he knew he'd screwed up. He nodded when Ronan said 'for you', then finally began the task of undoing Mars' straps. He held out his arm, bent at the elbow, so Ronan could pull himself up into a sitting position and then he pulled the smaller idiot into an embrace, kissed his head, and backed the fuck up. "Don't try ta walk yet," he ordered, firmly. He could have his space and his freedom, but he needed to eat and wait a while before actually leaving the bed. "Any requests?" The elder Murphy began to poke a bit for any hankerings Ronan might've had, but the only thing Mars seemed to crave at that moment was liberation. "Don't make me get ya oatmeal."
