What does this tell us? Well, not a whole lot, but we can speculate a few things.
1. if hoggers received it from Time Lord, he would have almost certainly picked two teammates to pass it off on. That would have suggested J-23 as his teammate. However, if that was the case, why would J-23 then pass it off to me (not mafia) or naslund.is.king? Doesn't make too much sense unless J-23 was going for some ultra-tricky play by recklessly passing it off.
With this in mind, we can probably say that J-23 is not a member of the mafia (although, he obviously still remains a candidate for 3P). Likewise, we can infer that hoggers probably didn't receive it either.
2. If Kurisu received it from Time Lord (and I believe it is very likely he did), all we know right now is that he would have chosen J-23 as an option but we would have no idea as to why. Luckily for us, he is still alive so... @Kurisu, if you received the medkit in R2, can you tell us who you passed the medkit off on? If you answer, can you elaborate as to why you picked J-23/the other person?
A green Kurisu should have no problems providing this info to the town. Let's hope he does so.
