And this defeats your whole "there is a child inside the house, we can't fight here" logic. If there is a child inside the house, she is still in danger. No, you don't let her come in contact with this being. At all. We attack now, where we have the maximum element of surprise, and a possible ally.
No she is not.
Kattrina wouldnt need to take a hostage if she was confident of winning a fight inside Old Man Mathews wards without prohibitive losses. She isnt going to start a fight here if she can help it.
The only way the kids risk increases is if we turn this place into a freefire zone.
And critically, her grandfather thinks so too, or his message would be "Get my grandchild out of here while I try to buy time" or " Go for help while I try to stall her".
Yes. And that's why we have to attack here. At all times later, she'll have more intel and prep against us. We lose in intel and prep. We lose hard at this point. So, we have to fight now.
People don't get "summon panoply" for free. We do. This is the time to strike.
1)Thats frankly not a concern.
We havent showed anything she has any way of finding out, and Mathews knows nothing about what we can or cannot do.
Furthermore our capabilities will keep evolving with each month that passes.
We're a baby. We're growing fast.
Meantime, as soon as we drive off, we literally have the opportunity to pick up the phone and call Gard for information and if she's wanted by Odin's people. And clarify that Odin wont be pissed if we get shanked.
Or get our father's backup. Or get Dresden out of jail.
2)Dresden wears armor by wearing a trenchcoat.
Cowl wore an enchanted robe to the Darkhallow. Kattrina is wearing a jacket that looks enchanted.
Do you think a woman who drove a luxury car here is wearing a studded jacket in the middle of summer for warmth?
The woman is almost certainly wearing magic armor right now.
No, she can threaten him by existing. She can't get him to cooperate by threatening him. Not long term. Kidnapping his grandchild and holding her hostage ensures his cooperation.
No she could not. Thats self-evident.
If she was strong enough to have just rolled him, she wouldnt have bothered with hostage taking. She'd have showed up at his house and threatened him and his kids. But at his home, behind his wards, Old Man Mathews is enough of a threat that she didnt think she could threaten him successfully, or win a fight easily, if at all. And she certainly couldnt get his cooperation.
THATS why she kidnapped Cindy first.
This is a constant of Dresdenverse magic
Sorcerers behind defenses on prepared ground are that much more potent than people attacking them. Thats why the White Council's defenses at Ediburgh need something like a god to crack.
Thats why Quintus Cassius was able to body Dresden in open combat but Dresden behind his wards was untouchable.
