For those of you who have already watched Chapter 6 of Volume 4 (to be frank, who hasn't at this point?) and have sat to analyze the information present, I'm sure many of you remember how Tyrian, right before turning to Ruby in their conversation referred to Jaune as interesting. Interesting. Such an obscure and ambiguous comment from him, yet so... insightful? I'm not not quite sure how, but it just is.
-He could be referring to Jaune's lineage as an Arc, as it has been heavily implied from many aspects and comments from him that his family is at least fairly well known. His inheritance as an Arc could be more interesting to the more... interesting persons of Remnant than we originally thought. During the initial fight, Tyrian insanely latches onto Jaune's shield and stares at Jaune dead in the face for a good few seconds, notably his eyes, before continuing his rampage. Could he recognize the young Arc from these stories?
-Another interesting thought is that Tyrian could be capable of reading into people's auras and has noticed how immensely large Jaune's is. I don't believe that this random theory can be proven right now, but a thought to be considered for in the future.
-Jaune has mentioned before that a past family member had fought in the Great War, which was highlighted by the protection of art and self-expression, and the fight against discrimination over the entire Faunus race. We can probably guess that this is a very sensitive topic for most Faunus, and probably acts as a grounds for hate from Faunus against Atlas and Mistral. Currently, where Jaune is from is unknown, but could his family live in Mistral, or did once upon a time. If the Arcs were famous warriors and one of them fought in the Great War, could it be possible that Tyrian would find it interesting to find an Arc boy alongside his target. Far-fetched? Possibly.
These are my thoughts and speculations. What are yours? What are your thoughts about Tyrian's motives and internal musings of the blond boy? What do you think is Jaune's newest significance here that could play a major role in the story later on? So many questions, very few answers... I love it.
