In this contribution, I reflect on the relationship between language, affect, materiality and power in qualitative research and interview situations in multilingual-intercultural contexts. I argue that through an assemblage approach, apparent challenges or shortcomings of working in a foreign language can be reinterpreted as veritable lines of flight, in which meaning is co-produced and power relations are partially and temporarily reversed. Furthermore, I show how affect and materiality shape such interview situations and how assemblage thinking helps us to become attuned to both. The argument for assemblage thinking in the context of multilingual interview situations is exemplified by my own research on the relationship between climate change and (temporal forms of) displacement within the city of Bangkok (Kingdom of Thailand).
