“He wants to go home,” Meera told Bran. “He will not even try and fight his fate.1 He says the greendreams do not lie.”
I'm in total agreement with this, I think the quote invalidates the Jojen paste theory too. I may have been convinced by the point that maybe Meera was just expressing that it was a wish of Jojen's to be brought home and then another point but I think that is definitely not the case because Meera is expressing the two ideas in the same sentence. Remove the Meera told Bran put in for grammatical purposes and you get Meera saying "He wants to go home, he will not even try and fight his fate.". The idea that fighting his fate by Jojen not going home is linked in Meera's mind, not independent of each other. Jojen's obviously told her that her fate is linked to him going home.
I think its entirely possible some Jojen blood could be in the paste though. Whether voluntarily or involuntarily. I can see Bran being shielded from that information because Jojen's been trying to reassure him that he's doing the right thing by going into the weirwood.
Also Jojen's behavior when he continually goes up to the mouth of the cave even though its cold specifically mentions he does it during during daylight hours. That makes me think that he knows he will never see another summer ever again and wants to see what daylight he has left in his life. To me this is a clue that he knows he'll die during the winter and upcoming long night. Perhaps on the way home or at his home.
