Not to mention lying to Yuya about Yuzu being kidnapped by academia(even though he saw Yugo teleporting her) , which Yuya was pretty pissed off about. He even knew Dennis being from Adademia , which will be another source of anger for Yuya soon.
Keep in mind Reiji is a very "ends justify the means" sort of person. Even if he respected Yusho and hates his dad , he's is a closer "Like father, like son " than Yuya is.
In the past series , the protagonist thinks of the Kaiba-clone as a nakuma , and it's mutual even if the other won't admit. So far, Yuya's relationship with Reiji has only got worst (Yuya respected him initially since he knew his dad) and I doubt Reiji gives a flying fuck about it.
I wouldn't be suprised if after Yuzu and Yuya reunites , he's the reason they seperate once more, or uses her to activate Egao Yuya in his keikaku . That will be the last straw for Yuya, being the unforgivable person
The only other person is Yusho that might be able to insight that anger
