Juliet's style is completely unlike Aegis's. Aegis moves with - well - vicious precision, but there's no extra power behind her strikes. And her comfort with her motion is based on having had her exo from childhood, not from having acquired it as a sudden boost at age seventeen (which Aegis has not yet attained to begin with). Juliet is also fast - maybe faster - and also precise - maybe less so - but everything she does is predicated on the fact that she has overwhelming power to put behind her moves (even though she is in fact being gentle with Sue) and doesn't need to worry as much as an unaltered human about being hurt. Long practice with Sherlock also means she's particularly good at not telegraphing. Sherlock can still usually catch her preparing to act. Sue most likely can't.
And when somebody tells him he doesn't have to hold back, he believes them.
It's actually easier to hit Juliet than it is to hit Aegis. It just doesn't have as much effect.
Which just means he needs to try harder, right?
When he gets his balance back and sneaks in past her guard to get at her face, she gets a bloody nose. It doesn't look like it hurts her that much, but it's a mess. "Ick, hold it," she says, straight-arming him in the chest to put him on the ground in case he takes a moment to process the call to halt. "I thought I was getting used to the smell of blood, but it's in my nose, ick. Let's go in and I can clean up. Nicely done."
"Glad you enjoyed yourself," laughs Juliet, attempting to hold her face in such a way that the blood doesn't get on her shirt. She goes up to Bar and gets tissues and peroxide for the drops she missed, but she's already stopped actively bleeding by the time these things appear. "Okay, if you can give the Slayer a bloody nose, you can walk around Sunnydale with her for a bit, if you want. We probably won't find anything."
"I'm gonna pop up to the Belltower real quick - I just found this door and haven't been yet - but assuming it's empty and there's not much to catch up on in the book we can go straight after. You want another look at the book yourself?"
Up the stairs and into the Tower. It is unoccupied. Juliet catches up on the contents of the book and lets Sue read over her shoulder.
"Us Bells like to keep busy," says Juliet. She hands him the book so he can see what happened before the point where she last saw the records. "What's yours been up to? You could put in an update, we do like to keep up with one another."
"Man. Do all Whistles have handwriting like that, I wonder?"
"I think the others mostly have keys to the Belltower, so they could write in the book if they wanted to, but if they come in here without their Bells to have a reason to do that, I don't know about it. Probably they don't do anything that belongs in the book that their respective Bells aren't covering, anyway. We don't need a case-by-case record of how many times they've all hooked up."
"Although the time my Sherlock and Amariah and Amariah's Whistle and the relevant daemons all got a room might warrant a note just because it was exceptional. I only know about it because Amariah told me, didn't want me to get a nasty surprise about Sherlock non-monogamy. Sherlocks are a little lower-key on that topic than you guys." When Sue's done writing, she says, "Sunshine visitation time?"
And into Sunshine they go. "This is my house. There aren't any demons in it unless you count the domesticated one that gives me Slayer powers," says Juliet. "It's broad daylight, so we won't run into any vampires, but we probably wouldn't at night either after what I've done to the place besides my Sherlock. Other demons are sometimes out and about in the day, though." She closes the door, and reopens it to her closet. "Shoo into the hall for a sec, I originally opened this door to change my jeans."
She comes out wearing functionally similar jeans that she did not spill juice on during breakfast. "You're gonna attract attention on the street in that uniform. Do you care? I could loan you some old things that I don't care if they disappear when you wake up."
Juliet produces some shorts - all her jeans would be too short for him, however relaxed the fit elsewhere in the measurements - and a unisex T-shirt proclaiming affiliation with her stepfather's minor league baseball team, and she shoos herself into the hall.
"What, you just wear uniforms all the time?" Juliet asks, showing him down the stairs. "...If we meet anyone I know, which we probably won't, you're my old friend from Phoenix and you popped up here to see me while your family's in the area to go to Disneyland. Cover story could probably do with a name that isn't 'Sue'."
