Change the names of the characters in the following passages. The character Lillith should be changed to Gwenith and the character of Beth should be changed to Carol. Also, correct any subtle grammatical errors.

Beth was losing the argument, her sister Lillith was determined to proceed with this dangerous plan, Please Lil, this is dangerous, you could get really messed up if you try this.
Carol was losing the argument; her sister Gwenith was determined to proceed with this dangerous plan. Please Gwen, this is dangerous; you could get really messed up if you try this.
That's great. Thank you!
I'm glad I could help! Please let me know if there is anything else I can help you with!
