Episode 234- I will go with you as your future husband.

Eugene was about to nod at him when she realized she never mentioned anything relating to her being unable to feel physical pain. She stared at him with an odd face and asked, "How did you know?" 

Louis shrugged, "You don't react to pain." 

Unbeknownst to Eugene, when she was younger, he would sometimes pinch her to see if she would react, but she never did. The first time he pinched her,  it was because she was slightly annoying and he wanted to warn her to not annoy him, however, she didn't react at all. Later, he would poke her from time to time, only to realize that she didn't feel anything. The only time she would react was when he spoke to her, and that was when he realized that Eugene doesn't feel physical touches.

'Ah..' Eugene thought, 'So that's how he knew.'

Louis remembered something and added, "Well, there was one time when you felt pain."
