Since when was the roles reversed? Angel was usually the one to talk about his feelings and Spike not so much. Angel was doing nothing, but trying to take care of Willow and then everything exploded. He had a lot of pent up emotions that he needed to air, but there were other times and places for it. He was about to say something back to Spike when his attention was turned to Faith appearing out of no where. Funny enough, some alone time is exactly what Angel was trying to do too.
If there was one person that Angel was going to listen it it was Faith. Not because he was scared of her, but because he respected her more than anything. Angel held his hands up, still angry more than anything at Spike and jealous that Spike could be with Buffy and he couldn't. Any hostility and anger towards Buffy wasn't meant for her, but for Spike. She was supposed to be his girl always, but she was Spikes now. He turned his attention back to Willow, returning to her side he knelt down. "This will calm her down," he noticed the bottle before looking over at Buffy and Spike one last time before his attention was back to Willow.
