(Background for this: My headcanon for Python is that he has the torso of a human, but with a snake head and a tail instead of legs)
When he first met Python, Wels was adamant on defeating the hermit in battle. After all, he was a knight, and Python was a serpent. How could he pass up the opportunity to slay a serpent?
Python, however, thought Wels was absolutely adorable. He would constantly pester the knight just to watch him get all huffy. Every morning, Wels would draw his sword and challenge Python to a duel, and every time, Python would coil around Wels and coo at him like he was a puppy. Poor Wels couldn't stand it.
One day, Python finally accepted Wels' challenge. The duel took all morning, but eventually, Wels was decided as the victor. That is, until Python confessed to letting him win. His reasoning? The knight was too cute, he just HAD to give him the victory. Wels was irritated of course, but Python's "Bambi eyes" were enough to convince Wels to challenge the serpentine hermit to a date instead.
Even now, further into their relationship, Wels gets huffy when Python brings it up. He worked hard for that victory, then just to find out Python wasn't even fighting at full strength?
See, Python doesn't actually need to fight at full strength. He's a serpent. He's cooler than that. Wels would probably beat him with ease in a proper duel, but Python isn't going to give him the satisfaction of knowing it.
He much prefers coiling his hand into Wels' anyway.
