Stuck on two final quests

Good News and Find Words. I can’t find Aegon and I have been in all the old tunnels and can’t find the words or Mina… Please help!

Aegon is in the Underwater Caves. You get there from St. Aidan's Crypt.

You can buy the book of Words from the girl Mina there in the far mid east of the Old Tunnels if you have the quest, persuade of at least 12 and 75 gold. She's beyond a gate you need to lockpick (skill of at least 10).You may need to hit some breakable walls.

She's here:
