Poor little thing...
I feel more sorry for the family waiting for him at Southend. I love Whales, I've been on 3 Whale watching holidays and have done loads of research on them - there by far my favourite animals - I've even swam with them Australia! Lucky me!
Anyway, whenever a Whale gets stranded or lost the family will wait for them (In this case, his mother is at Southend) - They will wait for ages until they return - but alas, he will not return.
Very very sad.
