Right. Best not to delay. Uncorking the potion, he pressed his lips once more to Remus' temple and murmured 'I love you too,' against his ear, before downing it. A strange, tingling sensation took hold then, spreading through his limbs as he felt his body morphing. It was a bit like turning into an animagus, except when he was Padfoot, he still felt like he was in his own skin. However, right now he felt entirely foreign to himself. When he had finished shifting, he was a bit taller and more muscular, his dark hair was now a light, well groomed brown. He didn't take time to marvel at the change though as he was too concerned about Remus.
Wrapping one of Remus' blankets around him, he scooped him up and grabbed the bag of potions. "Hold on, love." he said, sucking in a breath and making sure he had a good hold on Remus before starting towards the door.
