Thread creep...
The guy just wants someone to help out his parents. Cut him some slack.
EK is pretty good about helping out those who require assistance, and will no doubt have someone on board who speaks their native tounge.
That being said, I think that it's a strange place to be looking fo ra passenger travelling on a particular flight who is willing to agree to help a couple of strangers on a ULR flt with a connection to Jingly.
There is also the ICE system which has more than enough channels showing movies in a dozen or more languages.
They won't need anyone to "keep them company".
The Dubai connection will be seem just like home anyway.
