Connor hesitates for a brief moment, his LED going red for just a second. Part of him was sure Ralph hadn't needed to injure himself to do this, but there weren't many other options besides meticulously opening one of his panels and essentially drinking right from a vein.
"I won't take much. Just enough to stabilize my system. But if you want me to stop at any point, tell me and I will."
He's actually quite gentle as he takes Ralph's hand in both of his. Carefully he brings it up to his mouth, mindful not to spill any. Even with it flowing naturally because of Ralph's system pushing it from the wound, Connor still sucks at it lightly, swallowing every time his mouth became full.
