The third point of view:
Neon didn't need a prophet to tell him that his position in Ailee's heart was threatened. He wanted to refuse the date badly but there was no other reason why he had to refuse Ailee hanging out with Theodore and she was determined to be with him. If he refused Ailee that freedom, it was obvious they would end up fighting and their relationship would suffer.
Moreover, it was better they had a date where he could have his eyes on them. Wasn't there a saying, "Keep your enemies close and your enemies closer" except that in this case, it was a competitor. But then, he would be there to monitor and supervise their date - it would be chaste.
"Of course, that's a good idea," Ailee agreed, happy to know that Neon consented to the date. She knew it, her senior year would be great!
"I could also use that opportunity to get to know your brother more," Theodore said, flashing his pearly white teeth at Neon.
