Since I've come into question for a few days now and the stalker telescope has resurfaced:
I am Alan the Average Joe, and the one ability that works out of my given three is item-making (household items only). Things I have made:
N1: vanity mirror (meant to seer other people but wasn't specific enough to the mods, noob mistake)
N2: 2 cans with string (communicated with DVMD, but she was apparently too busy IRL to respond much)
N3: TV remote (used on Zensing, proven accurate)
N4: defibrillator (used on RM)
N5: asked mods a question (testing one of my other "abilities"...ended up getting a silly answer, which I shared on the thread)
N6: stalker telescope (used on Gwen, got back "Jodie the lawyer", proven accurate)
N7: paper airplane to send a one-way message (sent something to WZ, but she ended up dying that night)
N8: rollerblades (moved to a different group)
N9: missed night deadline
N10: made a thing, getting results tonight. I'll share once I get my results.
My ability's limited in that I haven't been allowed to make affiliation- or ability-seering items, or assassin-type items. Unfortunately, I've shared all this info with Lupin and dyachei, but they've been offed. No one else in the "alliance" SOV put me in has been communicating with me (I'm in a different group, so I can't PM without items). I also don't trust anyone in my ostensible alliance except for Cyndia, because she was trusted by Lupin.
tl;dr I'd consider the stalker telescope reliable.
