"Third is unlocked by completing the werewolf storyline up until it's latest progression which is against the swamp creature in the forest."
Is it possible if you be a little more clear on this part?
yep, no problem! you gotta do the entire werewolf questline with Logan starting with,
1. after or before the I owe you a beer event Logan has 3 events to do other than that, these are the ones where you have Logan beat the shit out of the alpha, the one where you meet the swamp werewolves/fight them and then last is the fight against the swamp creature in the forest. for the second one you go to Logan's place in bareshade and talk with him, you should either get an option to wait a week for one of his events or get it right away and that event basically says, "somethings up with the werewolves and I wanna handle it but I hate the werewolves, you like intervening in other people's business so you fix this" and you then proceed to do that. (Also, I believe you have prolly already had Logan beat the shit out of the alpha before, which is a requirement for this scene, if not I can also say how to get that event too)
2. The entire swamp werewolf questline. it starts with as I said above Logan not wanting to handle it because he hates wolves and wants you to check it, you start by going into the wolves' den and discovering a piece of a swamp creature, which then prompts you to check out the dark swamp, then eventually you are prompted to visit the misty abyss. you go there and discover that there are swamp werewolves after going towards the tree thing that fucks you if you visit it without our homie from TOS and as I said discover the swamp werewolves. beat one and go talk to Logan.
3. Logan freaks the fuck out and gets mad at the swamp creatures or whatever is stealing his pack (his words not mine) and tries to go and beat the shit out of them, but you just need to sit there and say, "that's stupid we can handle this better." instead of yelling at him. he will kinda cool it and then voila, you go to your house at night, and he should just appear out of thin air.
and as a little extra suggestion, if you do everything EXCEPT the I owe you a beer event you can trigger the Logan visit at your home before that and miss out on a good bit of stuff, so I would suggest you do the "I owe you a beer" event asap if it's not already done.
thats not what gives you the heart, you go home AFTER you choose the remain calm and it also is nighttime. you should then get a new event which is Logan asking you to go with him out because he wants to handle some stuff. the end of this is where you get the third heart.
(Also thank you for doing some stuff as I was completely stuck as to why you weren't getting the chat option, sorry I couldn't help more on that.)
np, and it may take a minute as well so thank you for saying I can take my time, if you wanna you can also check out a guy named Ben Dover's guide and see if he has something for this event I'm missing that you need. it could find that thing I'm missing.
