Without moving too much, Greg hurriedly stretched to the side, grabbing the rubbish bin and pulled it towards them, then lifted it up and held it out for Sherlock, who was trying to say something but had to stop to clamp a hand over his mouth again as he turned a little green. He was shaking even harder now and groaned.
Meanwhile Greg was now really at a loss for what to do. He waited a bit, to see whether SHerlock needed to use the bin.

When Sherlock was doing a bit better, or at least wasn't covering his mouth anymore and the green had turned back to simply sickly pale, Lestrade carefully slid away from him and got up. WIth one gentle but swift motion, he lifted Sherlock up, princess style, which usually would have been hilarious, but right then he wasn't even thinking much about it. "I'm getting you back into bed." he stated and, surprised at how well he was doing lifting Sherlock and carrying him, got him back into his bedroom and on the bed. He piled pillows behind him and covered him with his blanket, then went to get the bin and place it right next to the bed, should it be needed again. 
Greg sat down at the side of the bed and looked Sherlock over. "Should I get you some more tea? I think Mrs.Hudson should have some that would be good for you stomach." he offered, then got up and turned up the heater. "I think you should try to sleep some more, even if you just doze off for a bit."
