As Alexis comes around the final corner of the run-down, abandoned manor, she sees Tamni'el continuing to scout. However, as she starts to head for him, the large wolf shows up. Hoping that she would avoid notice, she froze, but the wolf sees through her feeble disguise, and looks straight at her.

Well, this is not good. Hopefully, however, this dog is vulnerable to magic

Surprise round: Alexis casts sleep

Assuming the sleep spell works, Alexis will go to the wolf, and next round, coup de grace the wolf with her longsword(Hopefully that is legal).
If the wolf does not go to sleep, Alexis will ready her sword, and send a message(the spell) to Anthony warning him of what she found, and asking the rest of the group to come(exact text will be done later)
