"My number is 23, I fight in the glyph room."
Ambro smiles. "I have much information about 'Adolin': His true name is River. He offered to help me kill you, if I so choose; I think he doesn't like you. He had a 'friend' or someone who recognized him, I didn't get to see the other mans face since I had to deal with some distractions. I saw River's number, it was 1. A few moments ago, I saw River talking with our two hosts, Jay'el was eavesdropping so he has better information from that point."
Ambro rushes out of the Arena.
Going to the bar, Ambro asks the bartender if Ambro could buy a mug from the bartender, preferably glass or ceramic. After much haggling, Ambro obtains a cracked glass mug for the rest of Ambro's coins.
Taking his mug to his room, Ambro wraps the mug in a rag of cloth, then smashes the mug into many small shards. Then, ties the bag of shards to his waist cord.
Surprise one complete.
Ambro unwraps one of his leather cords, then wraps it loosely around his hand to be used as a garrote.
Surprise two complete.
Pausing just before leaving, Ambro walks over to his bed and rips a sizable piece of the headboard off, making an impromptu stake. Surprise three. Just in case.
Ambro leaves the room, then returns to the waterfall arena, to go watch the first matches.
