Loki was coughing, he held the bucket, he was retching and he threw up a bit more. He knew Riza was upset and worried as well as Thor. He felt his brother's hand rubbing his back, he was slightly comforted. He closed his eyes for a bit. He heard his brother voice. "alright brother." he felt so sick.
He was laying back after and put bucket down carefully. He somehow trusted Riza would look after him. He really wished his brother would stay, but he knew he needed medicine.
