I heard from Fiona, Corrie and Bruno today. Not from Rudy.

It seems that Rudy had been taking his relationship with Fiona for granted, and Fiona being Fiona, decided to take a proactive approach to the situation. She completely camouflaged herself to become invisible to him and vanish from his life. (Fenton asked why she didn’t simply leave town, but she had classes to attend. The girl is super-conscientious.)
After a few days of missing her, Rudy finally admitted to her that the absence was affecting him. Of course, he didn’t exactly confess that intentionally; her final disguise was quite convincing.
Fiona returned Bruno’s clothes to him, and Rudy and Fiona had a somewhat-delayed Valentine’s Day.
