"What do you suppose is going on?" 20-year-old Baljeet inquired of his friends as they took their drinks to a large table. Phineas shook his head. "I don't know, 'Jeet. I received the same text everyone else did." He replied as he pulled out his phone and read it. "Please meet me at the coffee shop 2:45pm Friday."

Buford wrapped an arm around Milly. "We don't even know who sent the message." He complained. Adyson looked toward Ferb. "You tried tracing it?" Ferb nodded his reply. With a roll of her eyes, Gretchen commented. "We both tried tracing it. We both came up empty."

Everyone took their seats and the door to the coffee shop opened and a tall, twenty-something man wearing a fedora, walked in and made his way over to the group.

All eyes turned to the newcomer. "Phineas, Ferb… everyone." He began. Phineas stood up, extended his hand and smiled. "It seems that you're familiar with us, do we actually know you?"

The newcomer nodded. "You used to call me Perry."
