I assume your talking about the second one, how long has it been "sprouted".
Once they pop up they are generally ok. I have had to help a couple of seeds out of their shell though. You have to be really careful not to tear anything I use tweezers and a magnifier to crack the shell open.
Bear in mind, my experience is somwhat limited in growing. I have planted a total of about 50 seeds.
At this point i wouldn't say you have much to lose by carefully removing the seed coat and seeing if it will make it... I wouldn't count on it at this point though, but you never know... worth a try
