as a verb suffix has two basic functions:
* Expressing temporal antecedence, as basically a synonym for (possibly contraction from?) -- A`[VERB]`B means "A `[VERB]`, _then_ B".
* Expressing conditionality, similar to English "if" \-- A`[VERB]`B means " _if_ A `[VERB]`, _then_ B".
You'll notice that these translate to almost the same thing in English. Whether to include the conditionality of "if...then", or only the temporality of "...then", is a matter of context.
In the specific context of your sample text, it seems that the "if" sense must be the one intended. Here's one possible translation:
> ****
> **What if** you picked some flowers, brought them along and gave them [to her]...?
