Using the subjunctive

In lesson 10.3 Roberto says "Bisogna che vadano a vedere in un’agenzia immobiliare che li possa consigliare." I understand him using vadano after bisogna che but do not understand why he used the sunjuctive for potere at the end. Why not "li puo consigliare"? Is it that any/all verbs that follows bisogna che, voliglo che, espero...... must be in the subjunctive? Thanks

Ciao Maycham in the example we conjugate the verb "potere" in the present subjunctive as it is placed in a dependant clauses preceded by the word che (that). If you would like to review the rules, please go to lesson 13.7 and 13.8 . I hope this helps :) Buon divertimento!
