Is there any drama with such scene?

Where FL or ML was glitching or something like that. 

It Doesn't matter why FL or ML was glitching.

If by glitching you mean a short malfunction then:

• +1 Sisyphus: The Myth
• Cross Fire 
• Extraordinary You 
• W 
• Memories of the Alhambra 

• Bad and Crazy - ML suddenly deviates from normal behaviour
• Ghost Doctor 
• Life on Mars -Struggle with reality and fiction and surroundings glitch
• Reset - The Effecs of Time travel take a toll
• My Holo Love - ML AI clone
