You are free to disagree, but he definitely doesn`t say "wir" cause he
is kind of asking a question "why" "wie". It doesn`t really makes sense
in that context. Yes there is a "k" but it is his pronounciation
(accent), not a word, and he say`s : (k)ranschleichen, which is short
for heranschleichen - sneak up.
Anyway,…

good job omnomnam, only kranz is not right - rather sneak up….
