[Waver freezes for a moment, eyes darting around before Archer hits the ground. Okay, he doesn't know what that feeling is, but it's demanding him to sit up and pay attention because he might be in some serious shit right now and maybe he should prepare to fight - or more sensibly, run like hell?

In other words, the usual heart attack friend or foe assessment of one Servant recognizing another for the first time. Even if Waver is somewhat of a special case in that regard.

Then the tension seeps out of his frame and Waver takes a moment to push some of the long hair hanging like a curtain over his face back over his shoulders. Okay, not friend but not inclined to be foe based on his words.

Hopefully. Depends on how shit his luck feels like being today.]

Some fur. [Waver holds up a small tuft.]

Some of the beast's blood. [Exhibit B - a splinter of wood covered in blood that couldn't have come from the pigeons. That goes pinched in his fingers along with the fur.]

One noxious energy trail. [Ayakashi energy is... distinctive to say the least.]

And... [One eyebrow raises finely.] Someone who's hopefully here to help.[A beat.] Unless you're just here to check out what all the ruckus was about.

[Mind the snark? Waver runs on snark, minding it or not. He can take it. Hopefully Archer doesn't mind it being dished back.]
