Silent Spear here

and just another quick shout out for Acw28 for guessing it correctly also Weiss dosen't want to see Jaune in shorts (Yet, Jk) she's just using it as an example of the temperature he can survive in oh but Jaune can survive in even colder temperatures for example he can bathe in tub of dry ice and it will be like a warm shower. Also can you please update Grimm Arc I enjoy the story.

Also Due to you mentioning it I'll give you Pyrrha's reaction but port showing whos boss will be a separate chapter

Pyrrha's reaction

As Pyrrha witness the inhumane act apon the Brute and the girl she soon saw a small snowflake float down landing before melting on her nose.

"Is this Snow!?!" Pyrrha said with shock on how it was beginning to as she looked around and saw ir was snowing all around 'Vale is truly a unique place to snow at thos time of the year.' Pyrrha thought before hearing a Girl yell out. "Snowball fight!!!!" said the girl "Snowball fight?" Pyrrha said before smile "This is going to be fun." Pyrrha said as she grabbed a handful of snow and through it. There you go.

Well this is Silent Spear Ghost Phantom saying
