[Phoenix, you can't be shifty about the subject of her death, that's her job!!! Regardless, while she doesn't need a charged magatama to know he's being shifty (unlike beanie version, this goofball is back to being an open book), but she can recognize now's not the time.]

[Look forward to an awkward conversation later, Phoenix!!!]

[In the meantime, she's definitely running hand in hand with him]

Okay, fine! Talk later, running now! Move your old bones!
