So while arriving in Nimbasa City in Black 2, I went straight for the Ferris Wheel ride to see who's there. It was Clerk Female Trisha. After defeating her and riding the ferries wheel with her, she mentioned her baby was kicking and that my trainer reminds her of a certain person.

Being curious, I load Black and ran straight for the Ferris wheel and Trisha was indeed there, not pregnant. After defeating her and being impressed by the trainer's strength, they ride the ferries wheel together. She claims she's not crying and wanted to stay next to my trainer until they were back down. She seemed quite captivated with him.

tl;dr Trainer Black and Clerk Trisha fucked and now Trisha is pregnant in Black 2. Possible Slowpoke, I felt like pointing it out regardless
