I don’t think he will give any info, he ain’t that dumb plus he already knows that the other guy will be Jk’s oppo. He will either be kidnapped so that Jk should be emotionally affected by his disappearance and not be able to focus in his next match. Worst again , so that he can’t use his jinx.
Another plot can be that , they will take Dan away from Jk and make Dan work for them. Since it seems like his Grandma will die , it’s possible that Jk will prolly give a damn care about it , which will make Dan to take a decision and abandon him and go to his oppos. (But for me , the other plot below is more possible)

Sh*t, don't tell me that message will lead to some misunderstanding that Dan gives information to their opponent cause god I don't want him to suffer more than he already is cuz that bastard jaekyung T T
