"So, it's called... boba?" Heisenberg asks, looking down at the drink in his hand and lifting it to look at the balls at the bottom of the cup, squinting behind his dark glasses.

You worked with Chris Redfield and the others, and somehow you got the job to try to help Heisenberg understand how normal humans acted. After trying to teach him laws, rules, and stuff like that, you decided to do something fun.

So, yes, you took him to get boba! He got Brown Sugar Milk Tea Boba, which you suggested because you had a feeling he would like that flavor.
