Comma before 'though' at end of sentence

[JimmyB]

Could someone please clarify whether or not a comma is required before 'though' when at the end of a sentence.

Examples:

1) 'I don't like apples. I am going to try this apple pie, though.'

2) 'You are still taking part, though?'


Thanks in advance for any reply.

[Casiopea]

though (adverb)

1. However; nevertheless
Ex: Snow is not predicted; we can expect some rain, though.

2. Informal Used as an intensive
Ex: Wouldn't that beat all, though?
