Yes, it's interesting. Dr. Hirano is in a very difficult position. He is the doctor who developed this experimental treatment (for which I added a link above, and in the OP, if anyone wants to read about it). He went over to England to examine Charlie and look through his actual medical data, talk to the parents and the caregivers, review all the scans and other data, etc. There is always the chance that he'll say that he feels he can't help Charlie, then they're back to square one. Or, if he thinks he can, they'll go forward (if the English courts allow), and all eyes will be on the situation for years to come. What if the treatment is ineffective? With the world watching? Will that harm Dr. Hirano's ability to continue research, thereby hindering his helping many others besides this one patient? Will research money dwindle? (Or maybe it will increase, idk.) Will he feel he let the parents down (and the Pope, the President, Congress, all those hopeful for a "cure")? It's a lot of pressure on him. My guess would be that if he thinks the situation is futile, he might just end it there by saying he wishes he could, but in good faith, he can't, although I'm sure it would be a very difficult thing for him to do, especially with the whole world watching. I wouldn't want to be him right now. (And saying prayers for all involved, including Dr. Hirano, that he will have the wisdom and clarity to make the right decision, whatever he thinks that is.)
